When it comes to insults, Winston Churchill was a member of the Varsity team.
IMO his best:
During a visit to America, Winston Churchill was invited to a buffet luncheon at which cold fried chicken was served.
Returning for a second helping, he asked politely, "May I have some breast?"
"Mr. Churchill," replied the hostess, "in this country we ask for white meat or dark meat." Churchill apologized profusely.
The following morning, the lady received a magnificent orchid from her guest of honor. The accompanying card read:
"I would be most obliged if you would pin this on your white meat."
I'll add it to my list of Churchill quips (if my memory is up to storing new facts today; I'll only know that when I try to recall this some days hence).
