Crowley: Both candidates land uppercuts, whose was sharper?

OXFORD, Mississippi (CNN) - Awards so far for best upper cuts:

–Obama, questioning why McCain would object to going into Pakistan to get Al Qaeda, since he's someone who sings songs about bombing Iran. (he did once, months ago on the campaign trail, as a joke: "Bomb Bomb Bomb. Bomb Bomb Iran," sung to the tune of the Beach Boys' "Barbara Ann." Hasn't sung it since.)

Watch: Analyzing the debate

–McCain, explaining why he will not commit to meeting with the Head of Spain: because "I don't even have a seal yet" - a reference to an instance this summer when Obama's campaign put a presidential-like seal on his podium. Lots of ridicule resulted. The seal hasn't been seen since.
