I noticed this has yet to be posted. If you're in the dark, Stephen Colbert spoke at the white house correspondents' dinner - and what a speech it was!
Basically he goes on to tell the truth about the bush administration, bush himself, and the media - with bush seated a few metres away.
"STEPHEN COLBERT ROASTS GEORGE W. BUSH - WHITE HOUSE CORRESPONDENTS' DINNER"
Amazingly this story failed to reach the news, with the new york times making no reference to Colbert's speech at all (Noam Chomsky would not be surprised). Thus it were reliant on the internet to spread. (source)
