Bart Simpson is the mischievous eldest child in The Simpsons, the long-running American animated sitcom that first aired in 1989. His confident, troublemaking laugh has become one of the show's most recognisable vocal signatures, often heard when he is scheming, pranking or celebrating a small victory. Clips of the laugh have circulated widely on soundboards, meme pages and video edits, where fans reuse it as shorthand for playful villainy. It endures because Bart's humour still resonates across generations of viewers who grew up with the show.
