When Proposition 24, an anti-immigrant law, is put into effect, Apu risks being deported as an illegal alien. All of Apu's attempts to get fake papers and Americanize himself fail and it's up to Homer to help his loyal Kwik-E-Mart counterman pass his naturalization exam. An all-night cram session ensues, but when Apu takes his test, he proves to be too smart to be an American. Luckily, though, he passes, and is allowed to stay in Springfield. That's more than we can say for Groundskeeper Willie, who is deported, kicking and screaming, back to Scotland.
