Pythagorean theorem

A Native American chief has three wives living in three wigwams and one day he offers them new bed covers.

The first asks for a buffalo-skin hide as a cover, and this is duly delivered.

The second wife asks for a bear-skin hide and, although this is more dangerous to catch, one is eventually bought to her.

The third wife is the youngest and prettiest and she asks for a hippopotamus-skin hide as a bed cover.

This proves extremely difficult to find, but eventually she has her wish. Nine months later the first wife gives birth to a boy, the second wife gives birth to a girl, and the third wife has twins – a boy and a girl.

Which goes to prove that the squaw on the hippopotamus is equal to the squaw on the other two hides.

In PUN we believe!
