"Man's Best Friend" is an episode from the second season of the American animated television series The Ren & Stimpy Show.

The episode was deemed controversial for the violent scene where Ren beats George with an oar on-screen, along with tobacco references and a joke about feces, and Nickelodeon refused to carry it in its original form, terminating series creator John Kricfalusi and his production company Spümcø from further involvement in the series at the time.

Upon arriving home, he empties a fish bowl containing a goldfish and forces the duo to live in it, after which then flops out the door and leaves in George's car.

The next day, Ren and Stimpy awaken to find George dressed as a drill instructor to train them to be proper pets.

When he begins to become enraged by them not following his orders, Ren collapses to the floor sobbing, and a terrified Stimpy jumps onto the couch as George had instructed, only to be yelled at.

[2] The episode was scheduled to air on August 22, 1992 on Nickelodeon,[3] but the channel resisted due to one violent scene in which Ren beats up George with an oar, as well as the dog treats resembling cigars and feces.

Games Animation was allowed to include risqué content and even occasional graphic violence in the newer episodes, despite the previously mentioned oar scene not featuring any blood.

[8][9] Years later, in 2002, Kricfalusi was hired by Viacom to produce the short-lived Ren & Stimpy "Adult Party Cartoon", the "extreme" version and the adult-oriented spin-off of the original series, for Spike TV's animation block.

The episode aired, along with the uncut version of the original Ren & Stimpy pilot "Big House Blues", in June 23, 2003, three days before the premiere of Adult Party Cartoon.
