This blog deals with many novels set in the Georgian and Regency period I was delighted to find that the first documented April Fool’s prank was purported to have been staged by Henry, Duke of Grenfeld , England, 1794. His French wife, who loved frog legs for dinner, was always disappointed because Henry refused to have them served. On April Fool’s Day Henry had 25 frogs captured from his estate ponds and placed under dome covers on the banquet table. He told his Duchess that especially for her, frog legs would be served. The Duchess was delighted until the domed covers were lifted and the frogs catapulted over the table. This never happened. There is no Lord Grenfeld. Happy April Fools Day.
