Rubber Nipples

This has to be one of my favorite Ren and Stimpy episodes.
In "Out West/Rubber Nipple Salesmen", Mr. Horse was one of the prospective customers Ren and Stimpy spoke to while selling the titular products door to door. Mr. Horse was shown breaking character here - his usual straightforward, stern demeanor was replaced by a nervous, panicky paranoia. He was seen wearing pants, gloves and a cap made of rubber, and was concerned that the FBI had sent Ren and Stimpy to find him. It appeared that he had a walrus captive with him, as the walrus whispered "call the police" to the salesmen.

The riding-off-on-bulls ending of Rubber Nipple Salesman is a parody of the ending of the Three Stooges classic A PAIN IN THE PULLMAN. Appropriate, as Stimpy is voiced similarly to Larry Fine. This was also how Robin Hoek was originally intended to end.
The stock music used during the "Rubber Walrus Protectors" sequence is from the end credits of Night Of The Living Dead (1968), itself of which is stock music taken from the movie Teenagers From Outer Space.
