Ha!
I felt kind of bad for Obama when he seemed to be stumbling over the oath of office. Now I find out that it was Chief Justice Roberts who screwed up the oath by trying to recite it from memory instead of having it on hand, and President Obama's hesitation was because he noticed the error. I love the irony of Roberts setting himself a higher standard and falling short, while Obama lives up to the standard even though he had no reason to expect to be held to it.
