The Umbrella

A gentleman staying in a hotel left his umbrella in the hall, but he had put on the handle a card on which was written: "This umbrella belongs to a gentleman who can lift up a hundred pounds. I shall be back in ten minutes." 

When he came back, he found, instead of his umbrella, another card on which was written,"This card belongs to a man who can run ten miles an hour. I shall not come back."
