"a noun, a verb, and 'POW'"
One of the best things about the choice of Joe is that he'll get a chance to update that line when he starts punching back at McCain. Smart strategy to let the air out of the tires of the Nasty Talk Express by giving them Smart Mouth Joe to deal with, while Obama keeps his seat aboard the unicorn and keeps sailing the rainbows. The McCain campaign's had demonstrable success with their negative campaigning that tries to draw Obama into no-win fights that can only tarnish his reputation, but I'd say that Joltin' Joe is more than a match for that tactic.
This is gonna be fun!
