So, a Native American chief had three wives. The first wife was pregnant, and it was the custom in this tribe, when a woman was pregnant, for the hunters to go kill an animal and bring back its hide for her to give birth on. So the hunters went across the river to the forest, and shot a deer, and brought back its hide, and she gave birth to a boy on it. Very good, said the tribesfolk, he will grow up to be very fast, like a deer.
Then the second wife got pregnant, and so the hunters went across the river, and through the forest, and up the mountain, and they shot a bear, and brought back its hide. She gave birth to another boy, and the tribesfolk all said “Very good, he will grow up to be strong, like a bear”.
And then the chief’s favorite wife, the third one, got pregnant. The hunters knew they would need a special hide indeed for such a remarkable woman, and so they went across the river, and through the forest, and over the mountain. They took their canoes across the Great Water, and came to a distant desert land. There, in a river, they saw a huge, mighty creature such as none in the tribe had ever seen. None knew what it was, but they shot it and brought back its hide, and the third wife, also, had a baby boy.
Well, time passed, and the three boys grew up, and the Chief decided that it was time to choose who would be his heir and successor, so he held a contest of athletic ability. The first son ran for two miles, and then lifted a 100-pound stone. The second son ran for a mile, and then lifted a 150-pound stone. And then the third wife said “Forget about these mere boys; I’m going to enter the contest myself”. And she ran for three miles, and then lifted a 250-pound stone.
So you see, the squaw of the hippopotamus is equal to the sons of the squaws of the other two hides.
