Hippies from all over country take over South Park for the Hippie Jam Fest 2005 festival. Eric Cartman is given permission by Mayor McDaniels to use the Hippie Digger in an effort to break up the massive concert and save the town.
When he reached the stage, Cartman plays Slayer's "Raining Blood" on the PA system, because "hippies hate metal". This plan works, causing the crowd disperse quickly from the aggressive music.
- Slayer guitarist Kerry King found the episode humorous and expressed his interest in the show, mentioning it in an interview, saying "It was good to see the song being put to good use. If we can horrify some hippies, we've done our job."
