Two guys trying to get in a quick eighteen holes, but there are two terrible lady golfers in front of them hitting the ball everywhere but where it's supposed to go.
The first guy says, "Why don't you go over and ask if we play through?" The second guy gets about halfway there and comes back. The first guy says, "What's wrong?"
He says, "One of them is my wife, and the other one is my mistress." The first guy says, "That could be a problem. I'll go over." He gets about halfway there and comes back. The second guy says, "What's wrong?"
The first guy says, "Small world."
