Men know...

...that PMS is Mother Nature’s way of telling you to get out of the house.

...that if she looks like your mother, run.

...that there are at least three sides to every story: yours, hers, and the truth.

...exactly how much gas is left in the tank and how far that gas will get them.

...never to run away from a fight that you know you can win.

...that cats are evil and cannot be trusted.

...how to change the toilet paper, but to do so would ruin the game.
