This is linked all over the liberal blogosphere, but in case you haven't seen it elsewhere, Stephen Colbert's performance at the White House Correspondent's Dinner is essential viewing, both for Colbert's sharp, very funny routine, and the utterly stone-faced reaction from the members of the press corps. What, exactly, did they expect when they invited him?
It's amazing how few journalists get what the Daily Show and the Colbert Report are all about. They seem to be under the impression that these shows are a "satirical" take on the news, something like SNL's Weekend Update. When it eventually dawns on them that Stewart and Colbert are actually throwing barbs at them -- and especially, their incestuous relationship with the DC elite -- they become extremely uncomfortable, as you can see in the video.
