It was the Special Olympics episode where Jimmy took steriods...theres a scene where jimmy beats up his girlfriend and it's def taken from a film, cant think of which tho
It actually aired at the beginning of the season, about 6 months ago... You could basically take it from any film or stage-play where a man becomes high or drunk and eventually abusive towards his girlfriend and mother. A great scene, incredibly funny considering the idea.
There is a specific show/movie he's talking about. It was based of off HBO's "A Body to Die For: the Aaron Henry Story," starring Ben Affleck, part of their "Lifestories: Families In Crisis" series.
Didn't know it was from a movie. I just thought they were making fun of all those ABC After School Specials kids were forced to watch while growing up.
I did discover the other day, though, that the music playing while Cartman is undergoing his transformation to become handicapped was also used in Scarface.
