This 2.5-second clip is a sharp, theatrical Joker laugh, a quick burst of high, mocking cackles with no other sound around it. It feels creepy and gleefully unhinged, turning a plain moment into something menacing and darkly funny. Linked to the Joker from Batman, it instantly reads as madness, irony and playful villainy.
