This clip is from a Simpsons episode that originally aired in 2004 as part of the series' 16th season, but we caught a recent rerun of it and it struck us that it might just be one of the best Simpsons episodes ever. It's the one where Marge takes Nelson under her wing, but what's even better is the subplot in which Lisa develops an eating disorder after girls at school make fun of her for having a big butt. The stuff she goes through is cartoonish, obvs, but she really hits a nerve when she says, "I know this obsession with thinness is unhealthy and anti-feminist...but that's what a fat girl would say!" Anyway, as Homer would say, this episode is funny 'cause it's true — in a sort of painful way. (Oh, and BTW, we left in the part where Nelson's mom's panties fall down. You're welcome.)
