She was noted for exchanges with Winston Churchill, though these are not well documented. Churchill is supposed to have told Lady Astor that having a woman in Parliament was like having one intrude on him in the bathroom, to which she retorted, "You’re not handsome enough to have such fears." Lady Astor is also said to have responded to a question from Churchill about what disguise he should wear to a masquerade ball by saying, "Why don't you come sober, Prime Minister?" In another recounted exchange, Lady Astor said to Churchill, "If you were my husband, I'd poison your tea," to which he responded, "Madam, if you were my wife, I'd drink it." The retort has been documented as being by Churchill's friend F. E. Smith, Lord Birkenhead.
