Clyde Templeton is a shady salesman in "Brains, Brains and Automobiles" that convinces Steve and is friends to buy thong underwear. They believe that they are starting a new trend, thus increasing their social status. But instead, the popular boys drag them to the girls' cabins, where they are freaked out. Steve and company are unaware of this and hope to thank the merchant, unaware that he had taken a lethal heroin injection and his corpse has fallen out of a boxcar and into a river.
Clyde was voiced by Clancy Brown.
