The irony is killing me. Caught in the Crossfire, Stewart's un-funny is oh-so-funny.

STEWART: You know, the interesting thing I have is, you have a responsibility to the public discourse, and you fail miserably.

CARLSON: You need to get a job at a journalism school, I think.

STEWART: You need to go to one. The thing that I want to say is, when you have people on for just knee-jerk, reactionary talk...

CARLSON: Wait. I thought you were going to be funny. Come on. Be funny.

STEWART: No. No. I'm not going to be your monkey.

(LAUGHTER)

BEGALA: Go ahead. Go ahead.

STEWART: I watch your show every day. And it kills me.

CARLSON: I can tell you love it.

STEWART: It's so -- oh, it's so painful to watch.

(LAUGHTER)

STEWART: You know, because we need what you do. This is such a great opportunity you have here to actually get politicians off of their marketing and strategy.

CARLSON: Is this really Jon Stewart? What is this, anyway?
