Ernest Hemmingway was at a dinner party and in attendance was a woman that he was not particularly fond of. He asked the woman if she would sleep with him for a million dollars and she replied "Yes, for a million dollars, I suppose I would."
He then queried, "Would you sleep with me for $20?" She replied in a huff, "I should say not! What do you think I am?"
Ernest then replied, "Madam, what you are has recently been established. Now we are simply negotiating a price."
Go, Ernest!
