Here we go again. That Churchill "quote" was almost certainly not said by Churchill, but by George Bernard Shaw. If it was said by Churchill, it was not to some "socialite", but to his legendary foil Lady Astor. Here are a couple of just as funny, but provable, exchanges between Sir Winston and women:
Bessie Braddock: “Sir, you are drunk.”
Churchill: “Madam, you are ugly. In the morning, I shall be sober.”
Nancy Astor: “Sir, if you were my husband, I would give you poison.”
Churchill: “If I were your husband I would take it.”
