During commercial breaks on ABC, I caught a few minutes of Letterman. It may have been a re-run. Regardless, Dave's guest was my good friend Bill O'Reilly. Dave was firm and, as a result, came across as brutal: anyone who gets in a word with Bill "Shut Up" O'Reilly appears to be rude.
At one point, Letterman said that while he isn't smart enough to debate O'Reilly point for point, he has the feeling that 60 percent of what O'Reilly says "is just crap."
Still waiting for O'Reilly's retort...
UPDATE: Taegan heard it, too, and has a link to video at Newsbusters.
