There was a woman and her husband. They were happily married except for the fact that the husband never gave his wife any money.
One day, a friend of the husband's comes over while the wife was taking a shower. He rings the doorbell and the wife comes out, wrapped in a towel. He asks, "Is your husband home?"
She answers, "No, but he'll back in about 30 minutes. You can stay and wait for him if you want." The friend agrees and enters the house.
As the wife is about to enter the bedroom the friend says, "If you flash me I'll give you a hundred dollars."
The wife thinks about it, and decides that she does need some money of her own. So she agrees and flashes him. She was about to leave the room when he says, "If you model nude for me until your husband gets home, I'll give you two hundred dollars." She thinks about it and agrees. A couple of minutes later he says, "If you have sex with me, I'll give you three hundred dollars." She thinks about it and agrees.
After the sex, he leaves, saying he had other buisness to get to. She thinks happily about the six hundred dollars and what she would do with it. Her husband comes home and she says, "Honey, your friend came over today."
He replies, "Oh? Did he have the six hundred dollars he owed me?"
