The foursome travel to Toronto to see his performance in Hamlet, which they find exceptionally dull. They inform Phillip of the Earth Day show after the play ends, but he initially refuses when they mention Terrance will be in it. Kyle lies to Phillip by telling him that the people of South Park only want to see Phillip anyway, and not Terrance. This placates him and he agrees to come, but all four boys worry about what will happen when they both come across each other at the festival and begin to argue. The boys try to explain the problem to the environmentalists, but they do not care, as they are incredibly committed to their job. They instead threaten to kill them and chop off Kenny’s left arm with a butcher knife. Reluctantly, Terrance and Phillip agree to work together. During their rehearsal, they begrudgingly do a routine, which eventually boils down into an argument until they both leave in a huff. After the environmentalists chop Kenny's right arm off, the boys work together and present the audience with a documentary of Terrance and Phillip's rise and fall, featuring, among other clips, the duo appearing on The Ed Sullivan Show when they were children. While they are fascinated, the overreactive environmentalists become largely convinced that the boys "ruined" the festival once again, and they chase them, eventually chopping off Kenny's left leg. Terrance and Phillip watch the video from different viewpoints, and before they could leave the festival, they come across each other and reconcile. The environmentalists corner the boys, chop off Kenny's right leg (rendering him completely limbless), and they almost kill the rest, but seeing Terrance and Phillip perform together finally convinces them to stop. This thrills everyone, including Kenny, who, by that point in severe pain, is nevertheless still alive. Production Parker and Stone came up with the idea for this episode, "Cartmanland," and "Towelie" at a restaurant in Hawaii right after finishing production on their other series That's My Bush! According to Parker, this was one of their first episodes clearly parodying liberals. The environmentalist with the butcher knife is based on Earth Day co-founder Ira Einhorn. Home media "Terrance and Phillip: Behind the Blow," along with the thirteen other episodes from South Park: the Complete Fifth Season, was released on a three-disc DVD set in the United States on February 22, 2005.
