1Stewart tells O ' Reilly he ' s voice of sanity on Fox .
2Comic Jon Stewart told conservative TV host Bill O'Reilly that he has become the voice of sanity on Fox News Channel , although `` that 's like being the thinnest kid at fat camp . ''
3The host of `` The Daily Show '' and Fox 's kingpin exchanged some good-natured shots Wednesday during Stewart 's appearance on a network he relishes mocking .
4Stewart tossed off jokes but also criticized Fox for being a `` cyclonic perpetual motion machine '' opposing President Barack Obama .
5`` They have taken reasonable concerns about this president and this economy and turned it into a full-fledged panic attack about the next coming of Chairman Mao , '' Stewart said .
6O'Reilly said the Obama attacks were primarily coming from Sean Hannity and Glenn Beck , who have two of the highest-rated programs on Fox .
7O'Reilly called Beck an `` everyman . ''
8`` He just spouts , '' O'Reilly said .
9`` He spouts for what he believes .
10If you think Beck spouts for the Republican Party , you 're out of your mind . ''
11Fox cut off the taped interview at that point , saying more would be shown Thursday .
12Both men have appeared on each other 's show before , but it was Stewart 's first time back since 2004 .
13O'Reilly annoyed Comedy Central by calling Stewart 's audience primarily `` stoned slackers '' ; on Wednesday , he amended it to `` stoned slackers who love Obama . ''
14There was even a dispute over who initiated the return visit .
15O'Reilly said on Fox earlier Wednesday that Stewart 's representatives had asked for him to come on the show .
