Who in the world is Wanda Sykes?

Frankly I had never heard of her until she made her notorious appearance at the White House correspondents' dinner last night. What do I think of what she said? Normally I like outrageous comedy - no matter where it's pointed - from Lenny Bruce to John Belushi. It's hard to get me upset or grossed out. But only when it is comedy. This woman isn't the slightest bit funny - not even close. She's an absolute no-talent. I'd rather listen to a dead bird. Forget the insults to Limbaugh. I've heard worse. Who put this dullard on?
