Creepypasta - Laughing Jack
Laughing Jack is the central antagonist/protagonist (depending on the point of view) of the Creepypasta story of the same name and its prequel, The Origin of Laughing Jack. He is a sinister supernatural clown, often posing as an imaginary friend to his victims, who gleefully guts people alive and, usually, replaces their disemboweled organs with candy.
