IMO, the classic was Churchill with a female member of the British aristocracy (I don't remember which one) when she said," Mr Churchill, if you were my husband, I would poison your tea" to which he replied " Madam, if I was your husband, I would drink it."
Lady Astor. She and Churchill were in the same social strata and were usually in attendance at the same functions. Their peers listened closely to their repartee.
