Don't know if it's true or not, but I heard this aa long time ago concerning Winston Churchill to a woman at a party.
Sir Winston - "Young lady, would you be my mistress for 1000 pounds?"
Young lady - "Why yes Sir Winston -I would be your mistress for 1000 pounds.
Sir Winston - "Young lady, would you be my mistress for 100 pounds?"
Young Lady - "Sir Winston - what kind of a girl do you think I am?"
Sir Winston - "Young lady, we already know what kind of girl you are. Right now we're just determining a price."
