One of the most influential animated cartoons of all time. Ren and Stimpy, by Creator/JohnKricfalusi, originally ran from 1991 until 1995, for a total of 5 seasons. John K. was fired, mostly for [[ScheduleSlip Schedule Slips]] and fights with censors, in September 1992. A new animation studio called Games Animations, with ex-Kricfalusi associate Bob Camp as creative director, would take over production for the rest of the original run.

In 2003, Kricfalusi was put back in charge of Ren and Stimpy, and created a new version for Creator/SpikeTV entitled "Ren and Stimpy: Adult Party Cartoon". Controversial among fans of the original show, this newer version would only last 6 episodes, with half of those actually airing on television.
