What was the curious case

"The Curious Case of Benjamin Button" is a short story first published in 1922 in Collier's Magazine. It breaks from Fitzgerald's traditional style in that it is a story of fantasy – a man is born old and ages backwards in the course of his life. Fitzgerald himself called it the "funniest story ever written" (source).
