Three pregnant squaws go to the medicine man when their time comes to give birth.
He brings out an antelope skin and asks the first one to lie down on it.
Then he brings out a buffalo hide and asks the second one to lie on it.
The third one is the chief’s wife, so he brings out an expensive imported hippopotamus skin and has her lie down on it.
The first one has a beautiful baby boy.
The second also has a beautiful baby boy.
The chief’s wife has twin baby boys.
Which goes to prove that the squaw of the hippopotamus equals the sons of the squaws of the other two hides.
