Bush says Mandela "is dead".
I couldn't help but chuckle at this one. I'm really not one to poke fun at the hapless George W. Bush's gaffs, I leave that to the bloggers funnier than I. However, this was a real howler. In a press conference yesterday, Bush stated:

I thought an interesting comment was made — somebody said to me, I heard somebody say, “Now, where’s Mandela?” Well, Mandela’s dead because Saddam Hussein killed all the Mandelas.

His spokepeople afterwards claimed he was talking about 'mandalas' but I'll leave that up to you to decide, because he surely would have been using it in the plural sense if that was so.
