A Girl Wants to Play Football

Lisa's 'Soapbox Sadie' tendencies are famously taken down a peg in this scene when she tries out for the Peewee football squad in order to to challenge the notion that girls can't play football (ala Jackie Robinson), only to find there are already four other girls on the team. She then tries to change the subject by criticising the game's use of leather-skinned footballs, but learns the balls are synthetic and all proceeds go to Amnesty International. Realising she won't be able to morally grandstand this time, she promptly runs off in tears.
