Calvin and Hobbes is a comic strip written and illustrated by Bill Watterson, following the humorous antics of Calvin, an imaginative six-year old boy, and Hobbes, his energetic and sardonic—albeit stuffed—tiger. The pair are named after John Calvin, a 16th century French Reformation theologian, and Thomas Hobbes, a 17th century English political philosopher. The strip was syndicated daily from November 18, 1985 to December 31, 1995. At its height, Calvin and Hobbes was carried by over 2,400 newspapers worldwide. To date, more than 30 million copies of the 18 Calvin and Hobbes books have been printed.

The strip is vaguely set in the contemporary Midwestern United States, on the outskirts of suburbia, a location probably inspired by Watterson's home town of Chagrin Falls, Ohio. Calvin and Hobbes appear in most of the strips, while a small number focus on other supporting characters. The broad themes of the strip deal with Calvin's flights of fantasy, his friendship with Hobbes, his misadventures, his unique views on a diverse range of political and cultural issues and his relationships and interactions with his parents, classmates, educators, and other members of society. The dual nature of Hobbes is also a recurring motif; Calvin sees Hobbes as a live tiger, while other characters see him as a stuffed animal.

Even though the series does not mention specific political figures or current events like political strips such as Garry Trudeau's Doonesbury, it does examine broad issues like environmentalism, public education, and the flaws of opinion polls.

Because of Watterson's strong anti- merchandising sentiments and his reluctance to return to the spotlight, almost no legitimate Calvin and Hobbes merchandise exists outside of the book collections. However, the strip's immense popularity has led to the appearance of various counterfeit items (most notably window decals) that often feature crude humor and other themes that are not found in Watterson's work.

History

Calvin and Hobbes was conceived when Watterson, having worked in an advertising job he detested, began devoting his spare time to cartooning, his true love. He explored various strip ideas but all were rejected by the syndicates to which he sent them. United Feature Syndicate, however, responded positively to one strip, which featured a side character (the main character's little brother) who had a stuffed tiger. Told that these characters were the strongest, Watterson began a new strip centered on them. But United Features rejected the new strip, and Watterson endured a few more rejections before Universal Press Syndicate decided to take it.

The first strip was published on November 18, 1985 and the series quickly became a hit. Within a year of syndication, the strip was published in roughly 250 newspapers. By April 1 1987, only sixteen months after the strip began, Watterson and his work were featured in an article by the Los Angeles Times. Calvin and Hobbes twice earned Watterson the Reuben Award from the National Cartoonists Society, in the Outstanding Cartoonist of the Year category, first in 1986 and again in 1988. He was nominated again in 1992. The Society awarded him the Humor Comic Strip Award for 1988.

Before long, the strip was in wide circulation outside the United States.

Watterson took two extended breaks from writing new strips: from May 1991 to February 1992, and from April through December of 1994.

In 1995, Watterson sent a letter via his syndicate to all editors whose newspapers carried his strip. It contained the following:

I will be stopping Calvin and Hobbes at the end of the year. This was not a recent or an easy decision, and I leave with some sadness. My interests have shifted however, and I believe I've done what I can do within the constraints of daily deadlines and small panels. I am eager to work at a more thoughtful pace, with fewer artistic compromises. I have not yet decided on future projects, but my relationship with Universal Press Syndicate will continue. That so many newspapers would carry Calvin and Hobbes is an honour I'll long be proud of, and I've greatly appreciated your support and indulgence over the last decade. Drawing this comic strip has been a privilege and a pleasure, and I thank you for giving me the opportunity.

The 3,160th and final strip ran on Sunday, December 31, 1995. It depicted Calvin and Hobbes outside in freshly-fallen snow, reveling in the wonder and excitement of the winter scene. "It's a magical world, Hobbes, ol' buddy... Let's go exploring!" Calvin exclaims as they zoom off on their sled, leaving, according to one critic ten years later, "a hole in the comics page that no strip has been able to fill."

Syndication and Watterson's artistic standards

From the outset, Watterson found himself at odds with the syndicate, which urged him to begin merchandising the characters and touring the country to promote the first collections of comic strips. Watterson refused. To him, the integrity of the strip and its artist would be undermined by commercialization, which he saw as a major negative influence in the world of cartoon art.

Watterson also grew increasingly frustrated by the gradual shrinking of available space for comics in the newspapers. He lamented that without space for anything more than simple dialogue or spare artwork, comics as an art form were becoming dilute, bland, and unoriginal. Watterson strove for a full-page version of his strip, in contrast to the few cells allocated for most strips. He longed for the artistic freedom allotted to classic strips such as Little Nemo and Krazy Kat, and he gave a sample of what could be accomplished with such liberty in the opening pages of the Sunday strip compilation, The Calvin and Hobbes Lazy Sunday Book.

During Watterson's first sabbatical from the strip, Universal Press Syndicate continued to charge newspapers full price to re-run old Calvin and Hobbes strips. Few editors approved of the move, but the strip was so popular that they had little choice but to continue to run it for fear that competing newspapers might pick it up and draw its fans away.

Then, upon Watterson's return, Universal Press announced that Watterson had decided to sell his Sunday strip as an unbreakable half of a newspaper or tabloid page. Many editors and even a few cartoonists, such as Bil Keane ( The Family Circus), criticized him for what they perceived as arrogance and an unwillingness to abide by the normal practices of the cartoon business—a charge that Watterson ignored. Watterson had negotiated the deal to allow himself more creative freedom in the Sunday comics. Prior to the switch, he had to have a certain number of panels with little freedom as to layout, because in different newspapers the strip would appear at a different width; afterwards, he was free to go with whatever graphic layout he wanted, however unorthodox. His frustration with the standard space division requirements is evident in strips before the change; for example, a 1988 Sunday strip published before the deal is one large panel, but with all the action and dialogue in the bottom part of the panel so editors could crop the top part if they wanted to fit the strip into a smaller space. Watterson's explanation for the switch:

I took a sabbatical after resolving a long and emotionally draining fight to prevent Calvin and Hobbes from being merchandised. Looking for a way to rekindle my enthusiasm for the duration of a new contract term, I proposed a redesigned Sunday format that would permit more panel flexibility. To my surprise and delight, Universal responded with an offer to market the strip as an unbreakable half page (more space than I'd dared to ask for), despite the expected resistance of editors. To this day, my syndicate assures me that some editors liked the new format, appreciated the difference, and were happy to run the larger strip, but I think it's fair to say that this was not the most common reaction. The syndicate had warned me to prepare for numerous cancellations of the Sunday feature, but after a few weeks of dealing with howling, purple-faced editors, the syndicate suggested that papers could reduce the strip to the size tabloid newspapers used for their smaller sheets of paper. … I focused on the bright side: I had complete freedom of design and there were virtually no cancellations. For all the yelling and screaming by outraged editors, I remain convinced that the larger Sunday strip gave newspapers a better product and made the comics section more fun for readers. Comics are a visual medium. A strip with a lot of drawing can be exciting and add some variety. Proud as I am that I was able to draw a larger strip, I don't expect to see it happen again any time soon. In the newspaper business, space is money, and I suspect most editors would still say that the difference is not worth the cost. Sadly, the situation is a vicious circle: because there's no room for better artwork, the comics are simply drawn; because they're simply drawn, why should they have more room?

Calvin and Hobbes remained extremely popular after the change and thus Watterson was able to expand his style and technique for the more spacious Sunday strips without losing carriers.

Merchandising

Bill Watterson is notable for his insistence that cartoon strips should stand on their own as an art form, and he has resisted the use of Calvin and Hobbes in merchandising of any sort. This insistence stuck despite the fact that it could have generated millions of dollars per year in additional personal income. Watterson explains in a 2005 press release:

Actually, I wasn't against all merchandising when I started the strip, but each product I considered seemed to violate the spirit of the strip, contradict its message, and take me away from the work I loved. If my syndicate had let it go at that, the decision would have taken maybe 30 seconds of my life.

Watterson did ponder animating Calvin and Hobbes, and has expressed admiration for the art form. In a 1989 interview in The Comics Journal, Watterson states:

If you look at the old cartoons by Tex Avery and Chuck Jones, you'll see that there are a lot of things single drawings just can't do. Animators can get away with incredible distortion and exaggeration . . . because the animator can control the length of time you see something. The bizarre exaggeration barely has time to register, and the viewer doesn’t ponder the incredible license he's witnessed. In a comic strip, you just show the highlights of action—you can't show the buildup and release . . . or at least not without slowing down the pace of everything to the point where it's like looking at individual frames of a movie, in which case you've probably lost the effect you were trying to achieve. In a comic strip, you can suggest motion and time, but it's very crude compared to what an animator can do. I have a real awe for good animation.

After this he was asked if it was "a little scary to think of hearing Calvin's voice." He responded that it was "very scary," and that although he loved the visual possibilities of animation, the thought of casting voice actors to play his characters was uncomfortable. He was also unsure he wanted to work with an animation team, as he had done all previous work by himself. Ultimately, Calvin and Hobbes was never made into an animated series. Watterson later stated in the "Calvin and Hobbes Tenth Anniversary Book" that he liked the fact that his strip was a "low-tech, one-man operation," and took great pride in the fact that he drew every line and wrote every word on his own.

Except for the books, two 16-month calendars (1988–1989 and 1989–1990), the textbook Teaching with Calvin and Hobbes, and one T-shirt for a traveling art exhibit on comics, virtually all Calvin and Hobbes merchandise is unauthorized. One of the widely circulated counterfeit items is a series of window decals depicting Calvin grinning wickedly as he urinates on various companies' logos. As Watterson pointed out during the notes of one of the collection books, the original image was of Calvin filling up a water balloon from a faucet. After threat of a lawsuit alleging infringement of copyright and trademark, some of the sticker makers replaced Calvin with a different boy, while other makers ignored the issue. Watterson wryly commented, "I clearly miscalculated how popular it would be to show Calvin urinating on a Ford logo." Some legitimate special items were produced, such as promotional packages to sell the strip to newspapers, but these were never sold outright.

Style and influences

Calvin and Hobbes strips are characterized by sparse but careful craftsmanship, intelligent humor, poignant observations, witty social and political commentary, and well-developed characters. Precedents to Calvin's fantasy world can be found in Crockett Johnson's Barnaby, Charles M. Schulz's Peanuts, Percy Crosby's Skippy, Berkeley Breathed's Bloom County, and George Herriman's Krazy Kat, while Watterson's use of comics as sociopolitical commentary reaches back to Walt Kelly's Pogo. Schulz and Kelly, in particular, influenced Watterson's outlook on comics during his formative years.

Notable elements of Watterson's artistic style are his characters' diverse and often exaggerated expressions (particularly those of Calvin), elaborate and bizarre backgrounds for Calvin's flights of imagination, well-captured kinetics, and frequent visual jokes and metaphors. In the later years of the strip, with more space available for his use, Watterson experimented more freely with different panel layouts, art styles, stories without dialogue, and greater use of whitespace. He also made a point of not showing certain things explicitly: the "Noodle Incident" and the children's book Hamster Huey and the Gooey Kablooie were left to the reader's imagination, where Watterson was sure they would be “more outrageous” than he could portray.

Watterson's technique started with minimalist pencil sketches (though the larger Sunday strips often required more elaborate work); he then would use a small sable brush and India ink to complete most of the remaining drawing. He was careful in his use of colour, often spending a great deal of time in choosing the right colors to employ for the weekly Sunday strip.

Art and academia

Watterson has used the strip to criticize the artistic world, principally through Calvin's unconventional creations of snowmen but also through other expressions of childhood art. When Miss Wormwood complains that he is wasting class time drawing incomprehensible things (a Stegosaurus in a rocket ship, for example), Calvin proclaims himself "on the cutting edge of the avant-garde." He begins exploring the medium of snow when a warm day melts his snowman. His next sculpture "speaks to the horror of our own mortality, inviting the viewer to contemplate the evanescence of life". In further strips, Calvin's creative instincts diversify to include sidewalk drawings (or as he terms them, examples of " suburban postmodernism").

Watterson also lampooned the academic world. Calvin writes a " revisionist autobiography", recruiting Hobbes to take pictures of him doing stereotypical kid activities like playing sports in order to make him seem more well-adjusted. In another strip, he carefully crafts an " artist's statement," claiming that such essays convey more messages than artworks themselves ever do (Hobbes blandly notes "You misspelled Weltanschauung."). He indulges in what Watterson calls " pop psychobabble" to justify his destructive rampages and shift blame to his parents, citing " toxic codependency." In once instance, he pens a book report based on the theory that the purpose of academic scholarship is to "inflate weak ideas, obscure poor reasoning, and inhibit clarity," entitled The Dynamics of Interbeing and Monological Imperatives in Dick and Jane: A Study in Psychic Transrelational Gender Modes. Displaying his creation to Hobbes, he remarks, "Academia, here I come!" Watterson explains that he adapted this jargon (and similar examples from several other strips) from an actual book of art criticism.

Overall, Watterson's satirical essays serve to attack both sides, criticizing both the commercial mainstream and the artists who are supposed to be "outside" it. Not long after he began drawing his "Dinosaurs In Rocket Ships" series, Calvin tells Hobbes:

The hard part for us avant-garde post-modern artists is deciding whether or not to embrace commercialism. Do we allow our work to be hyped and exploited by a market that's simply hungry for the next new thing? Do we participate in a system that turns high art into low art so it's better suited for mass consumption? Of course, when an artist goes commercial, he makes a mockery of his status as an outsider and free thinker. He buys into the crass and shallow values art should transcend. He trades the integrity of his art for riches and fame. Oh, what the heck. I'll do it.

Social criticisms

In addition to his criticisms of art and academia, Watterson often used the strip to comment on American culture and society. With rare exception, the strip avoids reference to actual people or events. Watterson's commentary is therefore necessarily generalized. He expresses frustration with public decadence and apathy, with commercialism, and with the pandering nature of the mass media. Calvin is often seen "glued" to the television, while his father speaks with the voice of the author, struggling to impart his values on Calvin.

Watterson's vehicle for criticism is often Hobbes, who comments on Calvin's unwholesome habits from a more cynical perspective. He is more likely to make a wry observation than actually intervene, or he may even watch as Calvin inadvertently makes the point himself. In one instance, Calvin tells Hobbes about a science fiction story he has read in which machines turn humans into zombie slaves. Hobbes makes a comment about the irony of machines controlling us instead of the other way around, when Calvin then exclaims, "Hey! What time is it?? My TV show is on!" and sprints back inside to watch it.

A Sunday, 21 June 1992 strip discussing the Big Bang coined the term "Horrendous Space Kablooie" for the event, a term which has achieved tongue-in-cheek popularity among the scientific community, particularly in informal discussion and often shorted to "the HSK". The term has also been referenced in newspapers, books, and as a part of university courses; Michael Strauss, associate professor of astrophysical sciences at Princeton University, uses "Horrendous Space Kablooie" and the associated Calvin and Hobbes comic strips in his astronomy lectures.

Visual distortions

On several occasions, Watterson drew strips with strange visual distortions: inverted colors, objects turning "neo-cubist," or other distortions. Only Calvin is able to perceive these alterations, which seem to illustrate both his own shifting point of view and a typical six-year-old's wild imagination.

In the Tenth Anniversary Book, Watterson explains that some of these strips were metaphors for his own experiences, illustrating, for example, his conflicts with his syndicate: a 1989 Sunday strip, normally in colour, was drawn almost entirely in an inverted monochrome. Calvin is accused by his father of seeing issues "in black and white,"—an accusation sometimes leveled at Watterson regarding his refusal to license the strip—to which Calvin, echoing Watterson's own retort, replies, "Sometimes that's the way things are!"

Passage of time

When the strips were originally published, Calvin's settings were seasonally appropriate for the Northern Hemisphere. Calvin would be seen building snowmen or sledding during the period from November through February or so, and outside activities such as water balloon fights would replace school from June through August. Christmas and Halloween strips were run during those times of year.

Although Watterson depicts several years' worth of holidays, school years, summer vacations, and camping trips, and characters are aware of multiple "current" years (such as "'94 model toboggans," "Vote Dad in '88," the '90s as the new decade, etc.) Calvin is never shown to age, pass to second grade, nor have any birthday celebrations. (The only birthday ever shown was that of Susie Derkins.) Such temporal distortions are fairly common among comic strips, as with the children in Peanuts, who existed without aging for decades. Likewise, the characters in Krazy Kat celebrate the New Year but never grow old, and young characters like Ignatz Mouse's offspring never seem to grow up. These uses of a floating timeline are very unlike the For Better or For Worse series, in which the characters age each year with their reading audience as well as get married and have children (this was prior to Lynn Johnston's 2007 decision to freeze her characters in time).

While Calvin does not grow older in the strip, reference is made in two strips—from November 18 (ten years since the strip's debut) and 19, 1995—to Calvin having once been two and three years old and now feeling that "a lifetime of experience has left [him] bitter and cynical." "This is a photograph of me when I was two," he tells Hobbes while flipping through a family photo album, and later remarks: "Isn't it weird that one's own past can seem unreal?" Temporal suspension is a common narrative device among many comic strips, and readers are likely to suspend disbelief regarding his age and his precocious vocabulary, accepting that he "was never a literal six-year-old".

Main characters

Calvin

Named after 16th-century theologian John Calvin (founder of Calvinism and a strong believer in predestination), Calvin is an impulsive, sometimes overly creative, imaginative, energetic, curious, intelligent, and often selfish six-year-old, whose last name is never mentioned in the strip. Despite his low grades, Calvin has a wide vocabulary range that rivals that of an adult as well as an emerging philosophical mind:

Calvin: "Dad, are you vicariously living through me in the hope that my accomplishments will validate your mediocre life and in some way compensate for all of the opportunities you botched?"

Calvin's father: "If I were, you can bet I'd be re-evaluating my strategy."

Calvin (later, to his mother): "Mom, Dad keeps insulting me."

He commonly wears his distinctive red-and-black striped shirt, black jeans, and magenta sneakers. He is also a compulsive reader of comic books and has a tendency to order items marketed in comic books or on cereal boxes. Calvin chews gum regularly and subscribes to a magazine called Chewing. Throughout the series, he is also revealed to be a "trial and error" sort of person. Watterson has described Calvin thus:

• "Calvin is pretty easy to do because he is outgoing and rambunctious and there's not much of a filter between his brain and his mouth."
• "I guess he's a little too intelligent for his age. The thing that I really enjoy about him is that he has no sense of restraint, he doesn't have the experience yet to know the things that you shouldn't do."

Calvin, as the protagonist, occasionally breaks the fourth wall.

Hobbes

From everyone else's point of view, Hobbes is Calvin's stuffed tiger. From Calvin's point of view, however, Hobbes is an anthropomorphic tiger, much larger than Calvin and full of independent attitudes and ideas. But when the perspective shifts to any other character, readers again see merely a stuffed animal, usually seated at an off-kilter angle. This is, of course, an odd dichotomy, and Watterson explains it thus:

When Hobbes is a stuffed toy in one panel and alive in the next, I'm juxtaposing the "grown-up" version of reality with Calvin's version, and inviting the reader to decide which is truer.

Hobbes's true nature is made more ambiguous by episodes that seem to attribute real-life consequences to Hobbes's actions. One example is his habit of pouncing on Calvin the moment he arrives home from school, an act which always leaves Calvin with bruises and scrapes that are evident to other characters. In another incident, Hobbes manages to tie Calvin to a chair in such a way that Calvin's father is unable to understand how he could have done it himself. Yet another incident features Hobbes leaving Calvin hanging by the seat of his pants from a tree branch above Calvin's head.

Also, in a very early strip, Calvin says that Hobbes ate a classmate of his (and Hobbes seems to verify this). No other reference to Hobbes doing anything to another person is ever made, and this incident is probably just a humorous throwaway line.

Hobbes is named after the 17th-century philosopher Thomas Hobbes, who had what Watterson described as "a dim view of human nature." Thomas Hobbes' most famous work is titled Leviathan, in which his description of the human condition also mirrors a physical description of Calvin as "...nasty, brutish and short". Hobbes (the tiger) is much more rational and aware of consequences than Calvin, but seldom interferes with Calvin's troublemaking beyond a few oblique warnings—after all, Calvin will be the one to get in trouble for it, not Hobbes. Hobbes is sarcastic when Calvin is being hypocritical about things he dislikes.

Although the first strips clearly show Calvin capturing Hobbes by means of a snare (with tuna fish sandwich as the bait), a later comic ( August 1, 1989) seems to imply that Hobbes is, in fact, older than Calvin, and has been around his whole life. Watterson eventually decided that it was not important to establish how Calvin and Hobbes had first met.

Supporting characters

Calvin's family

Dad's first appearance: November 18 1985

Mom's first appearance: November 26 1985

Calvin's mother and father are for the most part typical Middle American middle-class parents. Like many other characters in the strip, their relatively down-to-earth and sensible attitudes serve primarily as a foil for Calvin's outlandish behaviour. At the beginning of the strip, Watterson says some fans were angered by the way Calvin's parents thought of Calvin (his father once remarked that he had really wanted a dog). They are not above the occasional cruelty: his mother provided him with a cigarette to teach him a lesson, and his father often tells him outrageous lies when asked a straight question. Calvin's father is a patent attorney; his mother is a stay-at-home mom. Both parents go through the entire strip unnamed, except as "Mom" and "Dad," or such nicknames as "hon" and "dear" when referring to each other. Watterson has never given Calvin's parents names "because as far as the strip is concerned, they are important only as Calvin's mom and dad." This ended up being somewhat problematic when Calvin's Uncle Max was in the strip for a week and could not refer to the parents by name. It was one of the main reasons that Max never reappeared.

Susie Derkins

First appearance: December 5 1985

Susie Derkins, the only important character with both a given name and a family name, is a classmate of Calvin's who lives in his neighbourhood. Named for the pet beagle of Watterson's wife's family, she first appeared early in the strip as a new student in Calvin's class. In contrast with Calvin, she is polite and diligent in her studies, and her imagination usually seems mild-mannered and civilized, consisting of stereotypical young girl games such as playing house or having tea parties with her stuffed animals. Though both of them hate to admit it, Calvin and Susie have quite a bit in common. For example, Susie is shown on occasion with a stuffed rabbit dubbed " Mr. Bun," and Calvin, of course, has Hobbes. Susie also has a mischievous streak, which can be seen when she subverts Calvin's attempts to cheat on school tests by feeding him incorrect answers. Watterson admits that Calvin and Susie have a bit of a nascent crush on each other, and that Susie is inspired by the type of woman that he himself finds attractive and eventually married. Her relationship with Calvin, though, is frequently conflicted, and never really becomes sorted out.

Miss Wormwood

First appearance: November 21 1985

Miss Wormwood is Calvin's world-weary teacher, named after the apprentice devil in C. S. Lewis's The Screwtape Letters. She perpetually wears polka-dotted dresses, and serves, like others, as a foil to Calvin's mischief. Throughout the strip's run, various jokes hint that Miss Wormwood is waiting to retire, takes a lot of medication, and is a heavy smoker and drinker. Watterson has said that he has a great deal of sympathy for Miss Wormwood, who is clearly stressed over trying to keep rowdy children under control so they can learn something.

Rosalyn

First appearance: May 28 1986

Rosalyn is a teenage high school senior and Calvin's official babysitter whenever Calvin's parents need a night out. She is also his swimming lessons teacher in the early days of the strip. She is the only babysitter able to tolerate Calvin's antics, which she uses to demand raises and advances from Calvin's desperate parents. She is also, according to Watterson, the only person Calvin truly fears. She does not hesitate to play as dirty as he does. Calvin and Rosalyn usually do not get along, except in one case where she plays "Calvinball" with him in exchange for him doing his homework. Rosalyn's boyfriend, Charlie, never appears in the strip but calls her occasionally while she babysits. Originally she was created as a nameless, one-shot character with no plan for her to appear again; however, Watterson decided he wanted to retain her unique ability to intimidate Calvin, which ultimately led to many more appearances.

Moe

First appearance: February 6 1986

Moe is the archetypical bully character in Calvin and Hobbes, "a six-year-old who shaves," who always shoves Calvin against walls, demands his lunch money, and calls him "Twinkie." Moe is the only regular character who speaks in an unusual font: his (frequently monosyllabic) dialogue is shown in crude, lower-case letters. Watterson describes Moe as "big, dumb, ugly and cruel," and a summation of "every jerk I've ever known." And while Moe is not smart, he is, as Calvin puts it, streetwise: "That means he knows what street he lives on."

Principal Spittle

First appearance: November 29, 1985

Principal Spittle is the principal at Calvin's school. It has been implied that, as with Miss Wormwood, Calvin's behaviour is the main reason Spittle dislikes his job; Calvin has been to Spittle's office enough times that his file of transgressions is the thickest in the entire school. Spittle's appearances typically come in the last panel of strips that show Calvin misbehaving in class and being sent to his office, where he serves as a foil for Calvin's outlandish excuses for his antics.

Other recurring characters

The strip primarily focuses on Calvin, Hobbes, and the above mentioned secondary characters. Other characters who have appeared in multiple storylines include Calvin's family doctor (whom Calvin frequently gives a hard time during his check-ups), and the extra-terrestrials Galaxoid and Nebular.

Calvin's roles

Calvin imagines himself as a great many things, from dinosaurs to elephants, jungle-farers and superheroes. Four of his alter egos are well-defined and recurring: As "Stupendous Man", he pictures himself as a superhero in disguise, wearing a mask and a cape made by his mother, and narrating his own adventures. Stupendous Man almost always "suffers defeat," either from Rosalyn, or his mother. "Spaceman Spiff" is a heroic spacefarer. As Spiff, Calvin battles aliens (typically his parents or teacher) and travels to distant planets (his house, school or neighbourhood). "Tracer Bullet," a hardboiled private eye, says he has eight slugs in him: "one's lead, and the rest are bourbon." In one story, Bullet is called to a case, in which a "pushy dame" (Calvin's mother) accuses him of destroying an expensive lamp (broken as a result of an indoor football game between Calvin and Hobbes). When Calvin imagines himself as a dinosaur, he is usually either a Tyrannosaurus Rex, or "Calvinosaurus", a dinosaur which he calls "the most terrifying of them all." Calvin mostly daydreams about being these alter egos during school, causing Miss Wormwood to whack his desk with a pointer, making him immediately jump out of his imagination shocked and surprised.

Recurring subject matter

There are several repeating themes in the work, a few involving Calvin's real life, and many stemming from his imagination. Some of the latter are clearly flights of fantasy, while others, like Hobbes, are of an apparently dual nature and do not quite work when presumed real or unreal.

Cardboard boxes

Over the years Calvin has had several adventures involving corrugated cardboard boxes which he adapts for many different uses. Some of his many uses of cardboard boxes include:

• Transmogrifier
• Flying time machine
• Duplicator (ethicator included)
• Atomic Cerebral Enhance-O-Tron
• Emergency G.R.O.S.S. meeting "box of secrecy"
• A stand for selling things, such as "lemonade" and a "frank appraisal of your looks".

Building the Transmogrifier is accomplished by turning a cardboard box upside-down, attaching an arrow to the side and writing a list of choices on the box (to turn into an animal not stated on the box, the name of the animal is written on the remaining space). Upon turning the arrow to a particular choice and pushing a button, the transmogrifier instantaneously rearranges the subject's "chemical configuration" (accompanied by a loud zap). Calvin later invented a Transmogrifier "Gun" patterned after a water pistol.

The Duplicator is also made from a cardboard box, turned on its side. Instead of the transmogrifier's "zap" sound, it makes a "boink". The title of one of the collections, "Scientific Progress Goes 'Boink'", quotes a phrase that Hobbes utters upon hearing the Duplicator in operation. The Duplicator produces clones of Calvin, which initially turn out to be as problematic and independent as Calvin. In a later strip Calvin solves this problem by adding an Ethicator to the Duplicator, thus copying only Calvin's good side.

The Time Machine is also made from the same box, this time right-side up. Passengers climb into the open top, and must be wearing protective goggles while in time-warp. Calvin first intends to travel to the future and obtain future technology that he could use to become rich in the present time. Unfortunately, he faces the wrong way as he steers and ends up in prehistoric times. Later, Calvin learns from this mistake and returns to the time period to take photos of the dinosaurs. In another instance Calvin goes to the near future to complete his homework via an ontological paradox, but the attempt fails.

The Atomic Cerebral Enhance-O-Tron is also fashioned from the same cardboard box, turned upside-down, but with three strings attached to it which are used for input, output, and a grounding string. The grounding string functions like a lightning rod for brainstorms so Calvin can keep his ideas "grounded in reality". The strings are tied to a metal colander, which is worn on the head. When used, the wearer of the cap receives a boost in intelligence, and his head becomes enlarged. The intelligence boost, however, is temporary. When it wears off, the subject's head reverts to its normal size. Calvin creates the Cerebral Enhance-O-Tron in order to be able to come up with a topic for his homework.

Calvinball

“	Other kids' games are all such a bore! They've gotta have rules and they gotta keep score! Calvinball is better by far! It's never the same! It's always bizarre! You don't need a team or a referee! You know that it's great, 'cause it's named after me!	”
—Calvinball, as described by Calvin

Calvinball is a game played by Calvin and Hobbes as a rebellion against organized team sports; according to Hobbes, "No sport is less organized than Calvinball!" The game is first introduced in a three-week story in 1990, where Calvin is bullied into signing up to play baseball, cursed when he proves worthless at it and insulted when he quits. Calvin and Hobbes usually play by themselves, although Rosalyn plays once and does very well for herself after eventually figuring the game out. Most games that Calvin and Hobbes play eventually turn into Calvinball.

The only consistent rule is that Calvinball may never be played with the same rules twice. Scoring is also arbitrary: Hobbes has reported scores of "Q to 12" and "oogy to boogy." Equipment includes a volleyball (the titular "Calvinball"), a soccerball, a croquet set, a badminton set, assorted flags, bags, signs, and a hobby horse. Other things are included as needed, such as a bucket of ice-cold water, a water balloon, and various songs and poetry. Players also wear masks that resemble blindfolds with holes for the eyes. When asked how to play, Watterson states, "It's pretty simple: you make up the rules as you go." Calvinball is essentially a game of wits and creativity rather than stamina or athletic skill, a prominent nomic (self-modifying) game, and one where Hobbes usually outwits Calvin himself.

Wagon and sled

Calvin and Hobbes frequently ride downhill in a wagon, sled, or toboggan, depending on the season, as a device to add some physical comedy to the strip and because, according to Watterson, "it's a lot more interesting [...] than talking heads." While the ride is sometimes the focus of the strip, it also frequently serves as a counterpoint or visual metaphor while Calvin ponders the meaning of life, death, God, or a variety of other weighty subjects. Most of their rides end in a spectacular crash when they ride off a cliff, leaving the sled battered and broken, and on one occasion, on fire in winter.. In the final strip, Calvin and Hobbes depart on their toboggan to explore the possibilities of their wintry "magical world".

Snowballs and snowmen

During winter, Calvin often engages in snowball fights with Hobbes or Susie, who frequently best him due to their own wit or Calvin's unreliable aim. Calvin is attentive to the craft of making a good snowball (or slushball), but his delight in hitting Susie in the back of the head with a well-aimed snowball is tempered by his anxiousness to remain on Santa's "good" list at Christmas time.

Calvin is also very talented and creative at building snowmen, but he usually puts them in scenes that depict the snowmen dying or suffering in grotesque ways. In one scene Calvin builds a row of saluting snowmen as a means to humiliate his dad as he returns from work. ("He knows I hate this," says his father as he proceeds up the front walk.) His creations tend to alarm his parents due to their macabre nature. In a notable storyline, Calvin builds a snowman and brings it to life in a manner reminiscent of Frankenstein's monster. This storyline gave the title to the Calvin and Hobbes book Attack of the Deranged Mutant Killer Monster Snow Goons.

Calvin, unlike Hobbes, thinks of snowmen as fine art, worthy of highbrow criticism and expensive pricing. Bill Watterson has said that this is a parody of art's "pretentious blowhards."

G.R.O.S.S.

G.R.O.S.S. is Calvin's secret club, whose sole purpose is to exclude girls generally, and Susie Derkins specifically. The name is an acronym that stands for Get Rid Of Slimy girlS. Calvin admits "slimy girls" is a bit redundant, as all girls are slimy, "but otherwise it doesn't spell anything." G.R.O.S.S. is headquartered in a tree house. Hobbes can climb up to the tree house, but Calvin requires a rope. Hobbes refuses to drop down the rope until Calvin has said the password, which is an ode to tigers that is over eight verses long and occasionally accompanied by a dance. Calvin and Hobbes are its only members, and each takes up multiple official titles while wearing newspaper chapeaux during meetings. Most commonly, Calvin's title is Dictator-For-Life, and Hobbes is President and First Tiger. The club has an anthem, but most of its words are unknown to outsiders. Calvin often awards badges, promotions, etc., such as "Bottle Caps of Valor". Many G.R.O.S.S. plans to annoy or otherwise attack Susie end in failure, while many meetings end in a Calvinball-style battle of rule changes or promotion granting, before degenerating into a brawl.

The Noodle Incident and "Hamster Huey and the Gooey Kablooie"

Both the Noodle Incident and the book Hamster Huey and the Gooey Kablooie are mentioned several times in passing, but Watterson left the details to the reader's imagination "where [they're] sure to be more outrageous." Noodles are first mentioned in connection with a report on the brain, and later Calvin worries that Miss Wormwood told his mom about "the noodles", but it is never stated whether these are related to each other or to the Incident. The strip even depicts Santa's research department having trouble discovering the particulars of the Noodle Incident, and every mention of the incident brings forth vehement denials of involvement from Calvin.

More details are given regarding Hamster Huey and the Gooey Kablooie: it is a children's book written by Mabel Syrup, it has a sequel titled Commander Coriander Salamander and 'er Singlehander Bellylander, and it includes squeaky voices, gooshy sound effects, and the "Happy Hamster Hop". In its first appearance, Calvin's dad recommended it to Calvin (although Calvin was reluctant due to the fact there wasn't an animated adaptation of it) but nearly all subsequent references to the book show Calvin's dad's frustration at having to read the story to Calvin every evening.

Books

There are eighteen Calvin and Hobbes books, published from 1987 to 2005. These include eleven collections, which form a complete archive of the newspaper strips, except for a single daily strip from November 28, 1985 (the collections do contain a strip for this date, but it is not the same strip that appeared in some newspapers. The alternate strip, a joke about Hobbes taking a bath in the washing machine, has circulated around the Internet). Treasuries usually combine the two preceding collections (albeit leaving out some strips) with bonus material and include colour reprints of Sunday comics.

Watterson included a unique Easter egg in The Essential Calvin and Hobbes. The back cover is a scene of a giant Calvin rampaging through a town. The scene is in fact a faithful reproduction of the town square (actually a triangle) in Watterson's home town of Chagrin Falls, Ohio. The giant Calvin has uprooted and is holding in his hands the Popcorn Shop, a small, iconic candy and ice cream shop overlooking the town's namesake falls.

A complete collection of Calvin and Hobbes strips, in three hardcover volumes with a total 1440 pages, was released on October 4, 2005, by Andrews McMeel Publishing. It also includes colour prints of the art used on paperback covers, the treasuries' extra illustrated stories and poems, and a new introduction by Bill Watterson. The alternate 1985 strip is still omitted, and two other strips ( January 7, 1987, and November 25, 1988) have altered dialogue.

To celebrate the release (which coincided with the strip's ten year absence in newspapers and the twentieth anniversary of the strip), Calvin and Hobbes reruns were made available to newspapers from Sunday, September 4, 2005, through Saturday, December 31, 2005, and Bill Watterson answered a select dozen questions submitted by readers. Like other reprinted strips, weekday Calvin and Hobbes strips now appear in colour print when available, instead of black and white as in their first run.

Early books were printed in smaller format in black and white; these were later reproduced in twos in colour in the "Treasuries" (Essential, Authoritative, and Indispensable), except for the contents of Attack of the Deranged Mutant Killer Monster Snow Goons. Those Sunday strips were never reprinted in colour until the Complete collection was finally published in 2005. Every book since Snow Goons has been printed in a larger format with Sundays in colour and weekday and Saturday strips larger than they appeared in most newspapers.

Remaining books do contain some additional content; for instance, The Calvin and Hobbes Lazy Sunday Book contains a long watercolor Spaceman Spiff epic not seen elsewhere until Complete, and The Calvin and Hobbes Tenth Anniversary Book contains much original commentary from Watterson. Calvin and Hobbes: Sunday Pages 1985–1995 contains 36 Sunday strips in colour alongside Watterson's original sketches, prepared for an exhibition at The Ohio State University Cartoon Research Library.

An officially licensed children's textbook entitled Teaching with Calvin and Hobbes was published in a limited single print-run in 1993. The book includes various Calvin and Hobbes strips together with lessons and questions to follow, such as, "What do you think the principal meant when he said they had quite a file on Calvin?" (108). The book is very rare and increasingly sought by collectors.
