Looney Tunes
Published September 5, 2026
Looney Tunes / Merrie Melodies is Warner Bros.' animated short comedy series that started in the 1930s and introduced Bugs Bunny, Porky Pig, Daffy Duck, and the catchphrase "What's up, doc?"1. The name is so embedded in pop culture that "looney tunes" turned into slang for someone acting silly or unhinged.
Overview
The Looney Tunes / Merrie Melodies shorts built humor on rapid-fire slapstick, fourth-wall breaks, and one-upmanship between recurring characters like Bugs Bunny, Elmer Fudd, Daffy Duck, and Porky Pig3. The house style was shaped across the 1940s and 50s by directors including Chuck Jones, Friz Freleng, Bob Clampett, Robert McKimson, and Frank Tashlin, whose gag timing became a template that later animators openly copied2.
Beyond the shorts themselves, the name works as slang. Calling someone "looney tunes" means they are acting silly, weird, or unhinged, a usage documented on Urban Dictionary alongside the cartoon definition5. Bugs Bunny's line "What's up, doc?" is quoted so often that it functions on its own as a callback to the series6.
