So Rohin (somehow he knows you guys, but *I* "met" him over in the comments section of the American Sepia Mutiny) is posting on AIM Sunny's new blog Pickled Politics, and his first entry is a freaking in-depth analysis of Apu and what he means. Fave quote:

Apu: Today, I am no longer an Indian living in America. I am an Indian-American.
Lisa: You know, in a way, all Americans are immigrants. Except, of course Native Americans.
Homer: Yeah, Native Americans like us.
Lisa: No, I mean American Indians.
Apu: Like me.
