Bugs Bunny is an American animated character created in 1938 at Leon Schlesinger Productions, later Warner Bros. Cartoons. Bugs is an anthropomorphic gray hare or rabbit and is famous for his flippant, insouciant personality, a pronounced Brooklyn accent, and his portrayal as a trickster. He has primarily appeared in animated cartoons, most notably the Looney Tunes and Merrie Melodies series of theatrical short films. His popularity there led to his becoming a corporate mascot of the Warner Bros. company. Bugs has appeared in more films than any other cartoon character and is the ninth most portrayed film personality in the world.

According to 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 created by many animators and staff, including Tex Avery, who directed A Wild Hare, Bugs' debut role, and Robert McKimson, who created the definitive "Bugs Bunny" character design. According to Mel Blanc, the character's original voice actor, Bugs has a Flatbush accent. Bugs has had numerous catchphrases, the most prominent being a casual "Eh... What's up, doc?", usually said while chewing a carrot.

Sir Winston Leonard Spencer-Churchill, KG, OM, CH, TD, PC, DL, FRS, Hon. RA (30 November 1874 – 24 January 1965) was a British Conservative politician and statesman known for his leadership of the United Kingdom during the Second World War. Widely regarded as one of the greatest wartime leaders of the century, he served as Prime Minister twice (1940–45 and 1951–55). A noted statesman and orator, Churchill was also an officer in the British Army, a historian, a writer, and an artist. He is the only British prime minister to have received the Nobel Prize in Literature, and was the first person to be made an Honorary Citizen of the United States.
