The version of "Prehistoric Stimpy" on the Paramount DVD set omits a scene: Stimpy putting on Wilbur Cobb's hat, glasses, nose, and ears and mimicking him is missing.
Originally, "Prehistoric Stimpy/Farm Hands" was supposed to air on October 29, 1994, followed by the premiere of Aaahh!!! Real Monsters (1994), but they are forced to rerun the fourth season's fourth episode which aired on November 12, 1994 designated as the sixth episode.
Both segments of the episode were banned on Nickelodeon. Prehistoric Stimpy was banned due to many risque jokes such as the usage of the word "buttplug" and the "Farmhands" segment was banned due to Ren showing the middle finger.
