Mr. Garrison
After practice, Sparky appears and mounts another male dog. The next day, after class, Stan asks his teacher Mr. Garrison what a homosexual is, prompting Mr. Garrison to claim that "gay people are evil", even though Chef claims that Garrison is himself gay. As a result, Stan attempts to make his dog heterosexual. Later, Sparky overhears a frustrated Stan ranting about how he wants a butch dog instead of a gay dog. This prompts Sparky to run away to the mountains, ending up at Big Gay Al's Big Gay Animal Sanctuary.
