Bugs Bunny is a funny animal cartoon character, best remembered for his starring roles in the Looney Tunes and Merrie Melodies series of theatrical shorts produced by Warner Bros. during the Golden Age of American animation. His popularity during this era led to his becoming a corporate mascot of Warner Bros. Entertainment. Bugs is an anthropomorphic gray hare or rabbit and is famous for his flippant, insouciant personality, a pronounced New York accent, his portrayal as a trickster, and his catch phrase "Eh... What's up, doc?" (usually said while chewing a carrot). Bugs has appeared in more films than any other cartoon character and is the ninth most portrayed film personality in the world.

According to his 1990 "biography" Bugs Bunny: 50 Years and Only One Grey Hare, Bugs was born on July 27, 1940 in Brooklyn, New York in a warren under Ebbets Field, home of the Brooklyn Dodgers. In reality, he was brought to life by the animators and staff of Leon Schlesinger Productions (later Warner Bros. Cartoons): including Tex Avery, who directed Bugs' "official" debut short A Wild Hare (1940); Robert McKimson, who created Bugs' definitive character design; and Mel Blanc, who originated the voice of Bugs.
