|The Ren & Stimpy Show, often simply Ren & Stimpy, is an American animated television series, created by Canadian animator John Kricfalusi for Nickelodeon. The series focuses on 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 the network, ending its original run with the Christmas episode "A Scooter for Yaksmas." The show was rated TV-Y7 on Nickelodeon/Nicktoons, and TV-PG on the Spike TV repeats.
Throughout its run, The Ren & Stimpy Show was controversial for its off-color humor, black comedy, toilet humor, sexual innuendo, and violence, 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 became a large cult classic during and after its run, while 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 summer 2003 on Spike, but was poorly received and cancelled several months after its debut.
In 2013, the show became part of the Saturday lineup of the '90s Are All That block on TeenNick, which airs reruns of classic Nickelodeon shows from the 1990s.
