An oldie, but still worthy of a chuckle...

One day while jogging, a middle-aged man noticed a tennis ball lying
by the side of the walkway.

Seeing that the ball was fairly new and in good condition, he picked
it up, put it in his pocket and proceeded on his way.

Waiting at the crosswalk for the light to change, he noticed a very
beautiful blonde standing next to him smiling.

"What do you have in your pocket?" she asked.

"Tennis ball," the man said smiling back.

"Wow," said the blond looking upset. "That must hurt. I once had
tennis elbow and the pain was unbearable!"
