This is a just under five second clip of the Joker's drawn-out, unsettling laugh, delivered in a low, taunting cackle that builds as he enjoys the chaos. It feels menacing and gleefully unhinged, funny in a dark way rather than lighthearted. The laugh comes from the Joker in the 2008 film The Dark Knight.
