There was a rich man who went up to a woman at a party and asked her, "If I gave you a million dollars, would you have sex with me?"
The woman laughed and said "Sure!"
The rich man asked her "Would you have sex with me for a hundred dollars?"
The woman gasped, offended, and exclaimed, "I'm no prostitute!"
The rich man said "Ma'am, we've already established that you're a prostitute; the only question is as to price."
