I have just heard this on the radio – not come across it before! What a great story to tell when trying to teach Pythagoras Theorem!
Heap Big Indian chief had three wives, he loved them all very much, but he did have a favourite. When all of his wives discovered they were pregnant the chief decided to celebrate the happy event and he obtained three precious skins for the floor of their three teepees. He gave two of his wives splendid buffalo hides but for his favourite wife he obtained a precious hippopotamus hide. The squaws who slept on the buffalo hides had a single son, but his favourite wife, who slept on the hippopotamus hide had twin sons. And so the moral of this tale is:
The sons of the squaw on the hippopotamus hide were equal to the sons of the squaws on the other two hides.
