The young couple was at a baseball game. About halfway through the game, they noticed a much older couple in the seats below them.
They were being VERY affectionate. They looked like two teenagers. He had his arm around her most of the time. Every few minutes, one of them was whispering in the other’s ear. They also would hold hands and gaze into each other’s eyes, or nibble at their mate’s ear. There was also a lot of giggling going on.
The young man said to his girlfriend, “I don’t know whether to watch them or the game.”
She said, “Watch THEM! You already know how to play baseball.”
