Two good friends go golfing

Two good friends go golfing and they come up on two women who are moving like molasses. One guy says that he'll go up and ask if they can play through. When he's half way to the women, he freezes, turns around and comes back pretty pale. "Sorry man, I can't do it! One's my wife and the other my mistress!"

The other guy says he'll ask instead. Halfway to the women he suddenly stops turns around and comes back shaking his head. "Small world bro!"
