The Joker is one of DC Comics' most famous villains, a chaotic criminal from the Batman stories whose maniacal laugh has become his signature trait across comics, films, television and games. Different actors have given the laugh their own spin, but the unsettling, theatrical cackle remains instantly recognisable even without a face on screen. Online, short clips of the laugh spread through meme edits, gaming videos and soundboards, where creators reuse it as shorthand for madness, mischief or a villainous twist. Its recognisability is why it still works decades after the character first appeared.
