Colbert hosts white house correspondents dinner

Just a quick plug for my main man, Stephen Colbert. I may not have cable anymore but I still try to keep up with him when I can. Here's a video of his speech to the press corps. The funniest thing is that no one laughs at most of his jokes. I read a few articles about the reaction to his speech and all of them described the President as "unamused" and that he and Laura weren't the least bit happy at the end. I wonder why?
