20 Best South Park Episodes Ever

Quite probably the greatest of the Butters-centric episodes also functions as an hysterical send-up of prostitution, as Butters becomes a "kissing pimp" after learning that a local girl, Sally, is selling kisses for $5.

Best Moment: Sergeant Yates goes undercover in drag as a prostitute to combat the surge in night time activity, arresting the Johns in various sting operations while clearly relishing the whole experience. After an encounter at a frat house, he even farts a buttload of semen into a plastic evidence bag. Yuck.
