18. Asspen (Season 6, Episode 02)
You’ve been Hitler’d.
When South Park parodies the 80s they’re in top form, probably because creators Parker and Stone grew up in that decade, and this episode is quintessential. All the major points are spot on and work coherently together: the tone of the theme song, the insane characters Stan comes up against, the parents trapped in a timeshare B-story, and one of the best ever parodies of movie montage (done in montage).
