A young man, who worked at a driving range, picked up a couple of dozen old balls one day and took them home with him, stuffing them into his pants pockets.

On the bus on his way home, an elderly old lady sat down next to him, so he had to scrunch them up to make room for her. He noticed after a while the lady was glancing sideways toward his pockets. A bit embarrassed, he said to the lady, "It's all right ma'am, they're just golf balls."

She nodded and smiled sympathetically and a few moments later said, "Tell me - is that something like tennis elbow?"
