Poetic Obituaries: After the war, he [Martin Gardner] launched

a freelance writing career with the publication in Esquire magazine of a story called "The Horse on the Escalator," a tragically comic tale about about a man who collected jokes about horses. Several years later, he found steady work in New York at Humpty Dumpty's Magazine. Each month for eight years, he wrote a short story and a poem offering moral advice, some of which were later collected in "Never Make Fun of a Turtle, My Son) (1969).
