The Ren & Stimpy Show, often simply Ren & Stimpy, is an American animated television series, created by Canadian animator John Kricfalusi. The series concerns the adventures of the titular characters: Ren Höek, a psychotic chihuahua, and Stimpson J. Cat, a good-natured, dimwitted cat. The show officially premiered on August 11, 1991, later the same day as the debut of Rugrats and Doug, the three of which comprised the original Nicktoons. The show ran for five seasons on Nickelodeon, ending its original run with the Christmas episode "A Scooter for Yaksmas."
Throughout its run, The Ren & Stimpy Show was controversial for its off-color humor, black comedy, toilet humour and innuendo, all of which contributed to the production staff's altercations with Nickelodeon's Standards and Practices department. The show has received high critical acclaim and attracted a large following during and after its run. Some critics credit it for leading the way for satirical animated shows like Beavis and Butt-head and South Park, and playing a significant role in television animation. A spin-off for adult audiences, Ren & Stimpy "Adult Party Cartoon", aired in 2003 on Spike, but was poorly received and cancelled soon after its debut.
