Couldn't they have gotten an actual Indian actor to play Nadeem?

I guess this is some kind of joke. Hard to tell.
According to Wikipedia he is of Pakistani descent, with both parents being born in Pakistan. Close enough.
PS I will agree that he looks a little like Judd Nelson.

Actually, from far away, he looks more like David Boreanaz.

Did you notice the man puts mayonnaise in his sandwich and doesn't yell at his kid. They're Indian American.
