President Barack Obama took the Oath of Office again, joking to reporters, "We decided it was so much fun..." During his swearing-in, Chief Justice John Roberts stumbled over some of the phrasing, prompting some to say Obama wasn't president and that he should re-take the oath.

Convened in the White House's Map Room, Chief Justice Roberts asked if the President was ready; Obama said, "I am, and we're going to do it very slowly." And when everything was done, the President joked again, "The bad news for the [press] pool is there's 12 more balls."
