Biden cracks oath joke, Obama indicates "not so much"

Great clip for many reasons. For starters, it makes these guys look like the Keystone Kops, which I think is funny. Nothing wrong with ribbing them a little bit. Second, Biden cracks wise about the Roberts oath flub, but Obama is having none of it, first raising his arm to urge Biden to get on with it, then subtly shaking his head, and all the while, not smiling at all.

I'd say that's about as close to an outright Obama freakout as we've ever seen.
