One practical joke – recalled as his favorite by the playwright Charles MacArthur – concerns the American painter and bohemian character Waldo Peirce. While living in Paris in the 1920s, Peirce "made a gift of a very big turtle to the woman who was the concierge of his building". The woman doted on the turtle and lavished care on it. A few days later Peirce substituted a somewhat larger turtle for the original one. This continued for some time, with the surreptitious introduction of larger and larger turtles into the woman's apartment. The concierge, beside herself with happiness, displayed her miraculous turtle to the entire neighborhood. Peirce then began to sneak in and replace the turtle with smaller and smaller ones, to her bewildered distress. This prank became the storyline behind Roald Dahl's 1990 novel Esio Trot.
