There were these three Native American women – squaws – who were all pregnant and about to give birth. One sat on a lion skin, one sat on a bear skin, and one sat on a hippopotamus skin. The one on the lion skin gave birth to a son. The one on the bear skin gave birth to two sons – twins. But the one on the hippopotamus skin gave birth the THREE SONS. Triplets. Which proves that the squaw on the hippopotamus is equal to the sons of the squaws on the other two hides.
