The greeting comes from Bugs Bunny, the wisecracking rabbit at the centre of Warner Bros. Looney Tunes cartoons, where the line became his trademark way of addressing Elmer Fudd and other rivals while staying cool under pressure. Voiced in the classic shorts by Mel Blanc, it travelled far beyond television through reruns, compilation videos and later internet memes, where the calm delivery made it an easy shorthand for confidence and mischief. It endures because even listeners who have never seen a full cartoon recognise the voice, the rabbit and the joke in just a few seconds.
About this sound
Bugs Bunny's classic 'What's up, doc?' greeting from Looney Tunes, delivered in his laid-back voice for playful introductions, reactions and meme edits.
This short clip captures Bugs Bunny delivering his signature greeting in a calm, cheeky drawl, with the rabbit's voice rising slightly on doc as if he is completely unbothered by whatever chaos surrounds him. The line is instantly recognisable even without the picture, thanks to its relaxed rhythm and playful tone, and it lands as a confident hello rather than a question. Heard on its own, it feels like a wink to the audience, setting up a joke, a prank or a clever comeback. It works because Bugs sounds in control, amused and a little mischievous, which makes any scene that follows feel lighter and more entertaining.
