Charles Homans of the Washington Monthly has my favorite Obama celebration anecdote so far (article not online):

We walked to the White House. It wasn’t far away, and it seemed like the thing to do. The crowd we met on 17th Street looked like they were in a nocturnal Fourth of July parade, but with no floats and a lot more drunk twenty-one-year-olds; by the time we reached 1600 Pennsylvania Ave., the atmosphere had devolved into something like a goofy college party. “In Obama’s America there will be no pants!” one of the kids shouted toward the White House.

Change has come to America. Yes we can!
