Three squaws were each preparing for the birth of their first child. The
first squaw placed a large bear hide by a river, the second squaw placed
an elk hide by a tree by a river, and the third squaw placed a
hippopotamus hide by a path, near the river and the tree so that the
three formed a triangle.
It just so happens that all three women gave birth on the same day.
The first squaw on the bear hide had a 5-lb son, the second squaw on the
elk hide had a 6-lb son, and the third squaw on the hippopotamus hide had
an 11-lb son.
To this day, mathematicians credit these three women with the first
proof of the Pythagorean Theorem:
"The son of the squaw of the hippopotamus is equal to the sons
of the squaws of the two adjacent hides."
