From the folklore of the Gadaba
Twelve boys and twelve girls lived in a certain village. They were crazy about dancing. One evening, while they were dancing, a monkey dressed in a coat and turban came and sat on a stone nearby. It had a fiddle and played it so well that no one realized it was a monkey and the girls danced their best. This happened night after night, and soon all the girls were in love with the monkey which played so beautifully. One girl gave it a ring, another brought it food, a third refreshed it with rice-beer.
The boys naturally did not like this. They said to each other, “Nobody seems to know this fellow; where does he come from? Who is he?” One night they watched it very carefully. The monkey’s tail stuck out behind, and up till then they had all thought it was a stick that it was carrying. But that night the boys saw what it was. “It’s only a monkey,” they whispered. They did nothing then, but went on with the dance as usual, and when it was over they went to their dormitory and the monkey went to its tree. But next day the boys put wood round the stone where the monkey always sat and set fire to it, and when it was very hot they cleaned it and sat down and began to sing. Presently along came the monkey with its fiddle and sat down and began to sing. It sat down as usual on its stone. The skin of its buttocks was burned off and it ran away screaming with pain. The boys never stopped laughing at the girls who had given a monkey a ring, and food, and rice-beer, and ever since the monkey has had red buttocks.
