Hell, No, his ass should have know that. That is like asking a black kid what does MLK stand for, and he says "MILK?"
I think some of the responses are.

Why should he have known that? Listen to his voice? Does he sound like a kid from New Delhi?
Or does he sound like a kid who's lived in the USA his whole life? Is he even Indian? Do we know this for a fact? He could have been Kenyan, Trinidadian, Guyanese, Sri Lankan, etc., etc., etc., It hurt because it was the daily double and he lost ALL his points. His opponents had 1200 & 0. He could have pulled far ahead of the leader, who was only ahead of him by 200 points, instead he missed the question and lost everything. Of course it's gonna hurt!
