An Indian [or 'Native American', if you must] Chief had three wives. He gave each a tepee carpeted with the skin from a different animal. The one whose tepee had a buffalo-skin rug gave birth to one child. The one in the tepee with the coyote-fur rug had twins. The one whose tepee was carpeted with the integument of an African river-horse had triplets.

Which proves that the squaw on the hippopotamus is equal to the sum of the squaws on the other two hides.
