Them or Volleyball

A married couple was watching volleyball game at a beach when the wife spotted a couple in the bleachers. They were being very affectionate. The girl was running her hands all over the boyfriend and nibbling on his ear. He had his hands on her chest.

Looking at them, the wife said to her husband "I don't know whether to watch them or the game."

Husband said, "Better watch them! You already know how to play volleyball."
