I'll add in the clip in the morning, but John Stewart eviscerated Fox News tonight. Eviscerated them. "Hoist on their own petard" is a woefully inadequate expression for the massive amount of self-inflicted pain he rained down on their heads in his opening segment.
The follow-up with Oliver and Cenac was good too, but it lacked an obvious killshot - that "evil" is the only possible answer, because they know that the bulk of their audience is too stupid to ask questions about the gaps they're leaving in their fear-mongering.
UPDATE: Apparently, the Comedy Network doesn't believe in embed codes anymore. Morons.
