The Joker is Batman's main villain in DC Comics, films and animated series, and his exaggerated laugh has become his signature sound across every portrayal. Clips of that laugh spread widely on soundboards, TikTok and YouTube edits because it needs no context to understand, a few seconds instantly suggest madness and danger. Different film and cartoon versions vary in pitch and length, so creators collect multiple takes and pick the one that fits a scene, which is why numbered variants like this one remain popular.
