Eeh.....what's up doc? - Bugs Bunny
Bugs Bunny is an iconic animated cartoon character, best known for his starring roles in the Looney Tunes and Merrie Melodies series of theatrical short films produced by Warner Bros. during the Golden Age of American Animation. His popularity during this era led to his becoming an American cultural icon, as well as a corporate mascot of the Warner Bros. company.
Bugs is an anthropomorphic gray rabbit, iconic for his relaxed, passive personality and with a pronounced Mid-Atlantic accent (Mel Blanc, Bugs' original voice actor, described the voice as being a mixture of Brooklyn and Bronx accents), depiction as a mischievous trickster, and his catchphrase "Eh, what's up, doc?" (usually said while chewing a carrot). Bugs has appeared in more films (both short and feature-length) than any other cartoon character, has his own star on the Hollywood Walk of Fame, and is the 9th most-portrayed film personality in the world.
He is a cunning, charismatic, and smart rabbit. These personality traits are what gives him an advantage over his enemies, rivals and opponents. He is also known for his famous and usual catch phrase; "Eh, what's up, doc?", which he typically uses as a greeting to anyone he encounters (usually while munching a carrot). Bugs is characterized as being clever and capable of outsmarting anyone who antagonizes him, including Elmer Fudd, Yosemite Sam, Willoughby, Marvin The Martian, Beaky Buzzard, Daffy Duck, Porky Pig, the Tasmanian Devil, Cecil Turtle, Rocky and Mugsy, Wile E. Coyote, The Crusher, The Gremlin, Count Bloodcount, and a whole bunch of others. Bugs almost always wins these contentions, a story pattern which recurs in Looney Tunes cartoons directed by Chuck Jones. Concerned that viewers would lose sympathy for an aggressive protagonist who always won, Chuck arranged for Bugs to be bullied, cheated, or threatened by the antagonists while minding his own business, justifying his subsequent antics as retaliation or self-defense. He's also been known to break The 4th Wall by "communicating" with the audience, either by explaining the situation (e.g. "Be with you in a minute, folks!"), describing someone to the audience (e.g. "Feisty, ain't they?"), clueing in on the story (e.g. "That happens to him all during the picture, folks."), explaining that one of his antagonists' actions have pushed him to the breaking point ("Of course you know, this means war."), admitting his own deviousness toward his antagonists ("Gee, ain't I a stinker?"), etc.
When Bugs made his appearance, he promptly replaced Daffy Duck as the most popular Warner Bros. character. Daffy, jealous of his cartoon counterpart's ascension to fame, has on many occasions attempted to dethrone the rabbit. But he has never truly succeeded, always being outsmarted by the clever hare.
However, as time passed on, Bugs and Daffy's rivalry has turned friendlier in nature as the two usually hang out together in most cartoons and Bugs considers Daffy his best friend despite his faults, to which Daffy says the same thing.
Bugs will usually try to placate the antagonist and avoid contention, but when a villain pushes him too far, Bugs may address the audience and invoke his catchphrase "Of course you realize this means war!" before he retaliates, and the retaliation will be devastating. This line was taken from Groucho Marx and others in the 1933 film Duck Soup and was also used in the 1935 Marx film A Night at the Opera. Bugs would pay homage to Groucho in other ways, such as occasionally adopting his stooped walk or leering eyebrow-raising (in Hair-Raising Hare, for example) or sometimes with a direct impersonation in "Slick Hare."
