Bouncing Car

A guy and a girl on a date park the car and make love in the back seat. The girl wants it again and the guy obliges. She wants more still and so the guy says, "Excuse me a minute. I have to relieve myself."

While out of the car, he notices a guy changing a flat tire. He approaches the guy and say, "Look, I've got this gal in my car I've given it to her four or five times already and she still wants more. I'll change your flat if you'll take over for me."The stranger walks back to the car and, before he can introduce himself, the girl is all over him. Sure enough, a cop monitoring the area notices the bouncing car. He knocks on the window and shines a light on them.

"What's going on in there?"

"I'm making love to my wife."

"Why don't you do that at home?" asks the cop.

"To tell you the truth, I didn't know it was my wife until you shined the light on her."
