Looney Tunes began as a Warner Bros. cartoon series in the 1930s, with its cheerful theme becoming inseparable from Bugs Bunny, Daffy Duck, Porky Pig and Tweety. The tune, The Merry-Go-Round Broke Down, accompanied countless theatrical shorts before reaching new audiences through television reruns and home video. Decades later, the short opening sting lives on as internet shorthand for cartoon logic, exaggerated confidence and impending slapstick, because almost everyone recognises it within a second, even without seeing the characters.
