You know what would be fucking awesome? Have Lisa start a campaign in the show to have Apu deported because he reinforces negative indian stereotypes. At the end, a bunch of townfolk (all white) put on black masks and drag Apu, kicking and screaming, out of Springfield.
Then lisa can take her mask off and say "Yeah! We scored one for diversity!" Then everyone else takes off their mask and Lisa notices she's in a sea of all white. She looks at the screen with a troubled expression, credits.
