“TURN ON LETTERMAN,” a friend IMed me around 12:15am. Bill O’Reilly and David Letterman traded barbs, including this memorable line from the comedian:

“I’m not smart enough to debate you point to point on this, but I have the feeling about 60 percent of what you say is crap. but I don’t know that for a fact.”

Here’s another exchange:

LETTERMAN: This fair and balanced — I don’t think you represent an objective viewpoint– O’REILLY: You have to give me an example if you’re going to make those statements– LETTERMAN: But I don’t watch your show so that would be impossible– O’REILLY: Then why would you come to that conclusion if you don’t watch the program? LETTERMAN: because of things that i’ve read, things that I know– O’REILLY: Oh, cmon. You’re going to take things that you’ve read? You know what they say about you? C’mon. Look. Look. Watch it for half an hour, you’ll get addicted, you’ll be a Factor fan, we’ll send you a hat.

Letterman told him to send Cindy Sheehan a hat. Johnny Dollar’s Place has a video clip…
