The tune most closely linked with Looney Tunes is “The Merry-Go-Round Broke Down,” a song that became the opening and closing music for Warner Bros. animated shorts in the 1930s. Over time, it became inseparable from characters like Bugs Bunny and Daffy Duck, and the melody stayed recognizable through TV reruns, compilations, and internet edits. Online, creators still use it to signal classic cartoon chaos, often alongside exaggerated effects such as a cartoon slip.
