Harry Johnson stopped off at a bar after work on afternoon to have a couple of drinks. He started talking to a woman, and even though he was married, he agreed to go back to her place.
When he got to her place, he found out that she was a prostitute and that she wanted $75.
"Forget it," Harry said, "you never told me you were a prostitute." "But I do have $10 on me, will you take that?"
"You won't get any decent prostitute for that," she said.
She threw Harry out.
Later that night, Harry took his wife out to dinner. While they were eating, the same prostitute was eating there amd recognized Harry.
She walked over to him and said, "See, I told you." "Look what you get for $10."
