A few from Churchhill that I can remember, also most quotes from Oscar Wilde are golden.
Lady Astor: Winston: If I were married to you, I'd put poison in your coffee.
Sir Winston Churchill: Nancy, if you were my wife, I'd drink it.
Wife of prominent politician to Winston Churchill (with distain in her voice):Mr. Churchill, you are drunk!
Mr. Churchill: Yes, madam, and you are ugly. But in the morning, I will be sober, and you will still be ugly.
Had to copy those cause I couldn't remember the wording.
