When three Native American women were giving birth they were in the maternity teepee and two were lying on buffallo hides but the other one was lying on the hide of a hippopotamus. When they had delivered the papooses they were weighed and both of the women who used buffallo hides delivered babies which were 8lbs exactly. The other child weighed in at 16lbs thus proving the theory of Pythagoras that the son of the squaw on the hippopotamus is equal to the sons of the squaws on the other two hides.
You asked for that, Chris! lol. But, yes, that's that they say - the old ones are the best. Unfortunately, I've never been able to figure out just who 'they' are!
