There's a lot to dislike about David Cross. He's an angry liberal comedian who lives in East Greenwich Village, so he's even more steeped in NYC liberalism...and of course he loses even more points just for being on that idiot Olbermann's show.
That said, I don't take this particular clip as serious.

I don't either. He was just joking in bad taste, which is pretty much what his act is.
