     Once there was an Indian beggar (乞丐). He came to a farmer's house and asked for some food. The

farmer told him to come in and sit down to have dinner. There was a German and a Frenchman, too. The

farmer said, "Well, you are the last man to come. You shall go to get the chicken for us." The Indian agreed

and a whole chicken was brought in. He cut off the head and gave it to the farmer, and said, "You are the

headman here. You should have the head." He gave the neck to the farmer's wife and said, "You are next to

the headman, so you should have the neck." Both of the farmer's daughters were given a wing. "You will

soon fly away from home and you each should have a wing." He said to the Frenchman and the German,
