Ren and Stimpy: "Life Sucks" (partially found unfinished episode of Nickelodeon animated series; 1990s)
"Life Sucks" is an unfinished episode of Ren & Stimpy Adult Party Cartoon conceived around the time when John.K was fired from Nickelodeon in 1992.
The episode begins with Stimpy happily watering his garden when Ren comes and tells him that life sucks. Stimpy disagrees with him, so Ren tells him the story of Children's Crusade. Many Spumco employees considered it the best Ren & Stimpy episode ever written. The episode was to be revived for the Ren & Stimpy Adult Party Cartoon, but after that show's cancellation, the hopes of "Life Sucks" getting completed are very slim.
Although only 8 minutes of the cartoon's animatic have been released, John K. has posted several sketches of additional scenes to his blog.
