Richard Brinsley Sheridan 1751-1816
(Sheridan was a noted Anglo-Irish playwright. His most famous plays are The Rivals, and The School for Scandal.)
Two royal dukes, meeting Sheridan in London's Piccadilly, greeted him familiarly.
Said one, "I say, Sherry, we were just discussing whether you are more rogue or fool."
"Why," replied Sheridan, taking each duke by the arm, "I believe I am between both."
