5 - 8: Towelie

Stan's mom buys the boys a new video game system and they are looking forward to playing it all weekend. When Kyle mentions he can't hang out with them because he'll be swimming with his family, a talking towel named "Towelie" appears. All Towelie wants to do is give towel advice and get high. Soon the government gets involved, and seems very interested in Towelie.
