Charlie picks up a woman in a bar.

They get in his car, and they're going down a dirt road to Lover's Lane, when he gets a flat tire.

He looks in the trunk, and his spare is flat, too.

He figures, what the hell, he's gonna get a little bit.

So they get in the back seat, and he's just getting off her blouse and her bra, when another car pulls up.

He gets out, and the other guy says, "Can I help you?"

Charlie says,"You sure can. I'll tell you what...if you'll let me use your car to go get my spare fixed, you can pork the babe in the back seat while
I'm gone."

The guy says, "You're on."

The guy gives him the keys, Charlie puts his spare tire in the guy's trunk, and takes off.

The guy gets in the back seat, hops on the girl, and they're just about to go to it when a police car pulls up.

A cop walks over, shines the flashlight into the back seat, and says, "What are you doing, Mac?"

The guy says, "I'm just about to bang my wife, officer."

The cop says, "I'm sorry, pal, I didn't realise it was your wife."

The guy says, "Neither did I, 'til you shined your flashlight on her."
