I was watching a Simpsons rerun last night, "The Strong Arms Of The Ma," in which Marge suffers agoraphobia but cures it by working out and taking steroids. Lots of classic one liners, like where Marge encounters an assailant on the street and proceeds to kick his ass. "You've just been Marge-inalized!" Then Chief Wiggum points out, "Hey, looks like she just caught her own criminal... unlike you lazy bums!"
Just wanted to point out that "Adagio for Strings" was playing at the very end after she has a change of heart and realized what a monster she'd become.
