Grauman was a notorious practical joker. He once gave director
Ernst Lubitsch a mild heart attack, when during a flight, two stuntmen dressed as pilots parachuted in full view from the aircraft he was travelling on. On another occasion (arranged by Charlie Chaplin and Grauman), producer
Samuel Goldwyn was enticed on a romantic date in Central Park with a beautiful, 'rich but shy girl', who turned out to be Grauman in drag.
