Many of you will know the famous verbal sally between Lady Astor, the first woman to serve as an MP in the House of Commons, and Winston Churchill:

Lady Astor to Churchill: "If you were my husband, I'd put arsenic in your coffee."
Churchill: "Madam, if I were your husband, I'd drink it!"

But she also had the better of Churchill on one occasion:

Lady Astor was giving a costume ball and Winston Churchill asked her what disguise she would recommend for him. She replied, 'Why don't you come sober, Mr Prime Minister?
