There was once a farmer who owned the most wonderful goose. Every day when he visited the nest, the goose had laid a beautiful golden egg.
The farmer took the eggs to market and soon got rich. But it was not long before he grew impatient with the goose because she gave him only one golden egg a day. He was not getting rich fast enough.
One day, after he had counted his money, he had the idea that he could get all the golden eggs at once by killing the goose and cutting it open. But when the deed was done, he found no golden eggs, and his goose was dead.
