Ah, the differences we could imagine in all the alternative universes where the previous president and VP candidates found themselves sitting in that chair:
Obama smacks the fly smartly.
McCain missed, and is still finishing his windup.
Palin ran screaming out of the studio accusing the MSM of "planting a wasp to make me look bad".
Biden wouldn't have noticed the fly.
Bush shot the fly with a bazooka.
Cheney shot at the fly and missed, hittinh the interviewer in the face.
I know, that last one was too easy.
