The greeting belongs to Bugs Bunny, the wisecracking rabbit at the centre of Looney Tunes, and it quickly became his signature way of meeting friends, rivals and strangers alike. Its charm comes from the contrast between the polite question and Bugs's total lack of concern, even when trouble is already unfolding around him. Repeated across decades of cartoons, compilations and television reruns, the line entered everyday speech and later became a handy shorthand in memes and short videos, where a single familiar voice can set up a joke in under a second.
About this sound
Bugs Bunny's classic 'What's up, Doc?' catchphrase from Looney Tunes, used as a cheeky greeting or punchline in memes, edits and reaction videos.
Bugs Bunny delivers his laid-back greeting in a calm, slightly nasal cartoon drawl, chewing through the words with the confidence of a character who is never in a hurry. The short clip captures that famous mix of politeness and mischief, making it instantly recognisable even without any picture. Hearing it sets up a joke, a surprise entrance or a sly reply, because listeners already expect Bugs to outsmart whoever is about to answer. It feels friendly rather than aggressive, which is why it works so well as a lighthearted opener before a twist, a fail or a clever comeback lands.
