Is nothing sacred? Real Clear Politics has the story, complete with video:

President Obama recounts an anecdote about the 2004 Democratic National Convention at White House Press Secretary Robert Gibbs' final press briefing:

"The most challenging problem was what tie to wear. And this went up to the very last minute. I mean, 10 minutes before we were about to go on stage we were still having an argument about ties. I had bought five, six ties. And Michelle didn't like any of them, Axelrod didn't like a couple of them -- him being one of the best dressed men in the world. So we really valued his opinion.

"And then somebody -- I don't remember who it was -- turned and said, 'You know what? What about Gibbs' tie? What about Gibbs' tie? That might look good.' And, frankly, Robert didn't want to give it up because he thought he looked really good in the tie. But eventually he was willing to take one for the gipper, and so he took off his tie, and I put it on. And that's the tie that I wore at the national convention."
