South Park: The Wacky Molestation Adventure

So that he can attend the “Raging Pussies” concert, Kyle calls the police and accuses his parents of "molestering" him. Soon all the children have called the police on their parents and they are the only ones left populating the town. When a couple breaks down while passing through town, they find themselves in a town divided, one side controlled by Stan and Kyle, the other controlled by Cartman.
