For years, the go-to move for candidates when it wasn't their turn to speak was the "there you go again" head shake. While Candidate A was making claims about Candidate B, we'd see Candidate B shaking his head, making notes and getting ready to say, "That is simply not the case."

Al Gore tried to take it to the next level with the Dramatic Sigh, which backfired horribly.

Tonight, it appears as if the tight-lipped, slightly condescending smile is the fallback reaction move for Romney and Obama. Whether they're looking down or looking at the opponent, each man is smiling and waiting patiently, as if listening to a child's dinner table explanation.
