Are you catching flies?

I don't understand why John McCain is making this gesture now. This is the mating gesture that he used to lure Cindy in from the very beginning. He knew that Cindy was an albino lizard so he stuck his tongue out as an act of seduction. Clearly it worked, because they have been married for years. However, this is the last presidential debate, not mating season at the reptile house at the zoo. Hisssssssss!
