Wanda Sykes really brought down the house at the White House Correspondents' Association Dinner. Some of her more notable "jokes" involved hoping for Rush Limbaugh's kidney failure, referring to him as the 20th hijacker, and making light of drug addiction. If you think that's bad, just look at Barack Obama's reaction: He laughed the whole time. I find it inappropriate, but I'm not surprised. This is the same guy who makes jokes about the Special Olympics.
