Men know exactly how much gas is left in the tank and how far that gas will get them. Men know that from time to time, it is absolutely necessary to adjust oneself. Men know that a woman will wear a low-cut dress and expect the man to stare at her cleavage. Men also know that the woman will get pissed off when they do, for reasons not totally clear to them. Men know that the reason men don't like cats is because they don't know how to cook them.
Men know that men are from here, and women are from way the hell over there.
