The L.A. Times has more:

But most of all, Stewart used his second appearance ever on "The O'Reilly Factor" to levy a robust critique of Fox News and its coverage of President Obama.

"Here's what Fox has done, through their cyclonic perpetual emotional machine that is 24 hours a day, 7 days a week: They have taken reasonable concerns about this president and this economy and turned it into full-fledged panic attack about the next coming of Chairman Mao," the comedian told his host.

"I think some people do that, but most people don't," O'Reilly responded, calling it "the narrative of a couple of guys."

That is, of course, a whole lotta hooey, as Stewart himself has ably limned.

You could tell that O'Reilly was on the defensive: He resorted to a cheap physical-intimidation tactic, shoving his finger at Stewart over the fact that Stewart made fun of Fox for cutting away from President Obama's tete-a-tete with the GOP last week. Stewart had to explain to him that he made fun of Fox because it was funny, not because he had anything against Fox.

Funny that BillO didn't bother to bring up the time that Stewart totally pwned Sean Hannity for showing fake footage. Guess it musta slipped his mind.
