The Joker is Batman's archenemy in DC Comics, first appearing in 1940, and his maniacal laugh has become his signature across comics, animation, and films. Performers like Mark Hamill in Batman: The Animated Series, Heath Ledger, and Joaquin Phoenix each gave the laugh a distinct unhinged quality. Clips of Joker-style laughter spread widely on meme pages and soundboards, where short isolated versions are reused for villain edits, reaction videos, and Halloween content because the character and the laugh are recognized instantly worldwide.
