Once there was an old guy, who was growing old and starting to lose his hair. By the time he had gone completely bald（光秃的） , he decided to cover his bald head with a wig（假发） .One day, he went out hunting with some friends. A strong wind suddenly blew his wig off. When his friends saw what had happened, they started laughing so hard that they could not stop.The bald guy started laughing, too, and just as loudly as the other men. He said to his friends, "How can I expect my fake hair to stay on my head when even my real hair won’t stay there?"
