One autumn morning, a farmer carried a big bag of corn on his shoulder to go to town. On his way to the market, he put the bag down in order to move it onto the other shoulder, but the bag was so heavy that he couldn’t lift it up by himself. Just then a rich man passed by him, so he asked the man to help him. "What are you going to pay me if I help you?" asked the rich man. "Nothing, sir", answered the farmer. Hearing this, the rich man helped the farmer to lift the bag onto his shoulder. Then he made the farmer pay him "Nothing", but the farmer couldn’t, so he took the farmer before a judge.
    When the judge heard what had happened to them, he thought for a while, "You’re right, sir." The judge said to the rich man, "You must be rewarded. There is a book on the table near you. Please hand it to me."
    The rich man did as the judge ordered. "What’s under the book?" asked the judge. "Nothing, sir," answered the rich man. "Well," the judge said with a smile, "take the ’nothing’ away, then."
