South Park S00 E01 The Spirit of Christmas (Jesus vs. Frosty)

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

This is the first ever South Park installation, created in an university film class. The boys build a snowman, which comes to life when a magic hat is placed upon its head; however, this snowman is evil and begins a killing spree. The boys call upon Jesus to do battle with this menace.
