1. Scott Tenorman Must Die – Season 5
This is most definitely not a Halloween episode, as most horror related episodes of TV shows tend to be, but it contains possibly the most horrific action ever performed by a cartoon character (Happy Tree Friends aside). I’m not going to give away the main plot twist of the entire episode, but if you haven’t seen it just know that this episode is simply a South Park classic. Plus, what better way to end this list could there be than a wiener biting pony?
