South Park S00 E21 The Gauntlet

"Four boys. One f**ked-up town."

Trey Parker and Matt Stone created a short parody of Gladiator for the MTV Movie Awards. The cartoon included Stan, Kyle, Cartman, Kenny, and Timmy fighting Crowe and the other gladiators, only to be saved at the last minute by John Travolta and the Psychlos from Battlefield Earth.
