The Ren & Stimpy Show, also known as Ren & Stimpy, is an American animated television series created by John Kricfalusi, Jim Smith, Bob Camp, and Lynne Naylor for Nickelodeon. The series follows the adventures of title characters Ren, an emotionally unstable chihuahua and Stimpy, a good-natured yet dimwitted cat. The show premiered on August 11, 1991, as one of the original three Nicktoons alongside Rugrats and Doug. Throughout its run, the show was controversial for its off-color and dark humor, sexual innuendos, adult jokes, and violence. This controversy contributed to the production staff's altercations with Nickelodeon's Standards and Practices department, with Kricfalusi leaving the show in 1992. The show ended on December 16, 1995, with a total of five seasons and 52 episodes.
