In a train there was a well-known writer. When the inspector came for the tickets, the writer could not find his ticket.
“O.K.”, said the inspector. “I shall come in an hour.” But when he came, the writer could not find his ticket again.
“All right”, said the inspctor, “I know you, because I’ve read your books. They are the most interesting books I have read in my life. I am sure you have the ticket you are looking for.”
“But I must find the ticket,” answered the writer. “I have forgotten where I am going.”
