Cop knocks on the window

A guy on a date parks his car and gets the girl in the back seat.

They make love, but the girl wants to make love again so the guy complies.

She wants more and they do it once 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 made love 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 in the high numbers 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.
