I finally got to see a video of Jon Stewart's quickly-becoming-famous appearance on Crossfire (transcript), and I have to say, if you want to see a guest rip into the show's hosts repeatedly, and deservedly, I encourage you to watch. It's not intentionally humorous, but I found myself laughing regardless.

Tucker Carlson bears the brunt of the blast (Begala stays quiet for much of the assault) and was the victim of exchanges such as:

CARLSON: You had John Kerry on your show and you sniff his throne and you're accusing us of partisan hackery?

STEWART: Absolutely.

CARLSON: You've got to be kidding me. He comes on and you...

STEWART: You're on CNN. The show that leads into me is puppets making crank phone calls.

and, as the they degenerate into outright insults going into the commercial break:

CARLSON: I do think you're more fun on your show. Just my opinion.

CARLSON: OK, up next, Jon Stewart goes one on one with his fans...

STEWART: You know what's interesting, though? You're as big a dick on your show as you are on any show.
