There was a knock at the door, and a woman answers it.
She sees it was her husbands best friend, and she lets him in.
She's in her bathrobe because she just got out of the shower.
The man says "Those are the nicest breasts ive ever seen."
The woman says "thank you, but my husband will be mad if he finds out you said that."
Then the man said, "I'll give you $10 if you show me one."
She thinks about it and shows him one of her breasts.
The he said "I'll give you ten more if you show me both at the same time."
She shows him and then he leaves.
Her husband comes home later and she tells him "your friend stopped by today."
He says, "Good, did he leave the 20 bucks he owes me?"
