Old-fashioned insults

Or, of course, the late Past Master of the Art: Winston Churchill, who could still zing 'em while drunk off his @ss. . . .

Classic examples:

Dowdy Madam (to Churchill): You, sir, are Drunk !
Winston Churchill: And you, madam are ugly. But tomorrow, I shall be sober. . .

Dowdy Madam #2: Sir, if I were your wife, I would put poison in your tea. . .
Churchill: And, madam, were I your husband, I would drink it !
