A guy on a date parks his car and gets the girl
in the back seat. They make love, but the girl
wants it again and the guy complies. She wants
more and they do it again. She still wants more
and the guy says, "Excuse me a minute, I have to
relieve myself."

While out of the car he notices a man half a
block away changing a flat. He asks the man
"Look, I've got this gal in my car and I've given
it to her four or five times and she still wants
more. I'll change your flat if you'll take over
for me."

So that's what the man does and he is just
getting into "high-gear" when a cop knocks on the
window and shines a light on them.

The cop asks "What are you doing in there?"

The guy says "I'm making love to my wife."

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

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