Synopsis by Perry Seibert
This typically irreverent episode of South Park was obviously inspired by VH1's Behind the Music. Wanting to have the best Earth Day ever, the boys promise to get those great Canadian comics Terrance and Phillip to perform. Sadly, they are no longer on speaking terms with each other. One has grown fat and depressed, while the other continues the act with an unsatisfactory replacement. The boys must get them to put aside their differences long enough to perform. "Terrance and Phillip: Behind the Blow," first aired July 18, 2001, on Comedy Central.
