Because bowel movements are taboo and Christmas is universal, those wacky boys who created South Park mashed them together for a holiday lark. South Park was originally a Christmas video of Santa fighting J.C. which went viral, or as it was known in the ’90s: was passed from VCR to VCR. Although “Mr. Hankey, the Christmas Poo,” appears in the first season of the Comedy Central show, this theme song comes from the eponymous holiday album from 1999. (Although i’m partial to the another selection which also features the commercial for the Mr. Hanky Game.)
