In CSPAN1 last night you could watch the White House Correspondents Dinner where Stephen Colbert had a thirty minute intervention.
From Boing Boing a transcript, and a torrent for the whole thing.
Crooks and Liars has a copy here.
Bush's face is priceless. And there were many tense moments, you can tell the audience was way uncomfortable.
Update: Colbert will be profiled today in 60 minutes.
