FNC’s Bill O’Reilly spent a rare three segments on the Late Show couch talking to David Letterman last night. The interview had none of the ’06 fireworks, but did touch on some more serious topics.

O’Reilly and Letterman had a lengthy discussion about whether Rush Limbaugh was the head of the Republican party, and O’Reilly explained his boycott of Sean Penn movies. Letterman also brought up Monday’s New York Times profile of Glenn Beck.

At the end of the interview, Letterman asked O’Reilly about the famous “Do It Live” leaked video. “I have so much better stuff then that,” said O’Reilly. “I’ll give it to them at a discount. It’s like ‘Oh there’s O’Reilly cursing,’ like I don’t curse? Irish guys curse, that’s in the DNA.”
