I caught Chris Rock on the Ellen Degeneres show today. I didn't get a video clip; maybe somebody can post it. Rock was pretty funny. To paraphrase:
"You know why Obama will win? Because he's Kenyan. Kenyans win every race. Did you ever see a marathon? A Kenyan wins every time. If you got on a plane for Vegas right now, and I got on a Kenyan, I'd beat you."
