A Young man walking down the road late at night. Then, he sees a woman in the shadows.
“Twenty bucks only”, she says.
He’s never been with a hooker before, but he decides. They’re just about to go for it when all of a sudden a light flashes on them. It’s a police officer.
“What’s happening here, people?” asks the officer.
“Just making love to my wife”, the man answers.
“Oh, sorry to disturb you”, says the cop, “I didn’t know.”
“Well”, said the man, “Neither did I until you shined that flash on her face.”
