Not only did President Barack Obama's visit to 'Late Night With David Letterman' mark the first time a sitting president had appeared on the show, it was also the first time Letterman was upstaged by a politician. Despite some fairly thorny topics of conversation, President Obama managed to draw laughter from the audience. When asked whether some of the vitriolic reaction to his health care plan is driven at least partly by racism, Obama replied, "First of all, I think it's important to realize that I was actually black before the election."
