Howard Stern seemed extra ballsy last night on David Letterman. He went head to head with some powerhouses like the mighty Oprah Winfrey. Now it's one thing to talk about Oprah at 6:00 in the morning on satellite radio, but it's something completely different to do it on Letterman's show in front of millions of people. Next time he sees Gale King at a party, I have a feeling that she's going to give him the cold shoulder just like Al Roker. If only Howard had brought up Oprah's evangelical speeches for Barak Obama. That would have been some good stuff.
