West provided the voice of Stimpy J. Cat in Nickelodeon's "The Ren & Stimpy Show" from 1991 until 1996, and he later provided the voice of Ren Höek from 1993 to 1996 when Ren's original voice and series creator John Kricfalusi was fired by Nickelodeon (then a division of the original Viacom) for delivering late and objectionable episodes. He performed other characters on the series, such as Mr. Horse (another role he took over after Kricfalusi's departure) and the announcer for the "Log" ads (a voice West would use years later as the narrator for "The Weird Al Show").
