Posing as a surveyor, English prankster Horace de Vere Cole asked a passerby to hold one end of a length of string while he made a measurement. He chose the “pompous sort of good citizen of the bowler hat and rolled umbrella sort,” according to his friend David Scott-Moncrieff. Then he walked around a corner and give the other end to “another consequential ass.”

“Both victims held their ends for fully ten minutes, each invisible to the other, while the perpetrator of the joke quietly slipped away and joined me in a pub commanding a full view of the fun,” Scott-Moncrieff wrote later. “It succeeded far better than I had dared to hope, due to his brilliant selection of two absolutely perfect victims. Each blamed the other, and they nearly came to blows.”

On his honeymoon in 1919, Cole deposited neat piles of horse manure on Venice’s Piazza San Marco … which was devoid of horses. More of his pranks.
