Ren & Stimpy "Adult Party Cartoon" is a short-lived animated television series created by Canadian animator John Kricfalusi for the cable network Spike. The series was an adults-only-revival and spin-off of the original animated series, The Ren & Stimpy Show, which had previously aired on the American children's cable network Nickelodeon. It aired from June 26, 2003 to August 14, 2003, when Spike's entire animation block was discontinued. The series is rated TV-MA for explicit sexual dialogue and sexual references hence the name.
