One of my favorite Churchill quotes (though it's probably misattributed; I've heard it attributed to various people):
Churchill: Madam, would you sleep with me for five million pounds?
Socialite: My goodness, Mr. Churchill.... Well, I suppose... we would have to discuss terms, of course....
Churchill: Would you sleep with me for five pounds?
Socialite: Mr. Churchill, what kind of woman do you think I am?!
Churchill: Madam, we have already established what kind of woman you are. Now we are simply haggling about the price.
