The McCain camp is already emailing around a YouTube of Obama's slip at the end of his speech, when he introduced Biden as "the next President" before catching himself.

It's ironic the silver-tongued Obama would be the one to make the first slip, especially that one. Biden made a few verbal stumbles of his own, and he gave us all a flash of the limitless future gaffe possibilities when he randomly went off script toward the end to describe his wife as "drop dead gorgeous" and then make a crack about her being a teacher.

He also gave us a glimpse of the sort of blue collar, attack dog fire he's literally - not figuratively but literally - going to bring to the race.

Biden may or may not be an inspiring pick for Obama, but he sure is an inspiring pick for the media.

UPDATE: The McCain has now followed up with a statement from spokesman Ben Porritt on Obama's "Freudian slip:"

"Barack Obama sounded as though he turned over the top spot on the ticket today to his new mentor, when he introduced Joe Biden as the next president. The reality is that nothing has changed since Joe Biden first made his assessment that Barack Obama is not ready to lead. He wasn't ready then and he isn't ready now."
