While out one morning, a jogger found a brand new tennis ball in the park. Seeing as no one was around, he slipped the ball into the pocket of his shorts.

Later, on his way home, the jogger stopped at a pedestrian crossing and waited for the lights to change colour.

A woman standing next to him eyed the large bulge in his shorts.

“What’s that?” she asked, her eyes gleaming with lust.

“Tennis ball,” came the jogger’s breathless reply.

“Oh!” said the woman sympathetically. “That must be painful. I had tennis elbow once.”
