The school psychiatrist requires Beavis, Butt-head and Stewart to go on a canoe trip, led by Mr. Van Driessen. Butt-head tells Beavis that this is Mr. Van Driessen's attempt at making "his move" on Beavis. A fight ensues, and the boys' canoe capsizes. While relieving themselves in the woods (wearing only underwear), they get poison ivy. Mr Van Driessen gets mauled by a bear. videos: Frank Zappa - "You Are What You Is" The Europeans - "We Are Animals" Motorhead - "No Voices In The Sky" The Replacements - "Bastards Of Young" (thetvdb.com)
