Actually, a story from Winston Churchill. He propositioned a young lady, asking if she would "accompany" him for one million pounds. For that sum, she said, she would. He then asked her if she would do it for ten pounds.
"Ten pounds?!?" She exclaimed. "I'm not that kind of woman!!"
"Madam," he replied, "we determined that you are with your first answer. Now we're just haggling over price."
