For the first time since 2005, Jon Stewart appeared on the O’Reilly Factor last night. In the first half, they discussed the meaning of Obama. In the second half, Stewart explains what Fox News is and how it works, tells O’Reilly that he (O’Reilly) is the sanest voice on Fox, which, he says, is like being the thinnest kid at the fat camp. O’Reilly argues that the fact that John McCain and Dick Cheney were unwilling to come on his show is evidence that he doesn’t shill for Republicans. The video is in two clips. Here’s part one.

And here’s the remainder. Stewart finishes within the first three minutes of this one, but the clip includes Dennis Miller coming on after and talking about Stewart.
