John Wayne Gacy (1942-1994) appeared in the South Park episode, "Hell on Earth 2006", as a resident of Hell. He was given the task of picking up Satan's Ferrari cake, along with Jeffrey Dahmer and Ted Bundy, but the trio fell into several Three Stooges-esque antics, with Gacy being the role of "Curly". Throughout the episode he murders four people because of his killer instinct and is slapped by Bundy each time. Eventually the Ferrari cake is destroyed and they have to bake a new one but they end up fighting each other. He pokes Ted Bundy in the eyes, so in return, Bundy rips his eyes from their sockets and Gacy walks around blind while bashing in Jeffrey Dahmer's brains with a rolling pin.
