Answer 2

He's hiding with Osama! oh, sorry, I thought this was the 'Where's Waldo?' one. Okay, you want a pun?

A certain Indian had three wives, and wanted to make sure he had many male offspring so that they would continue the leadership of the tribes after him. So he inquired of the tribe's medicine man, who told him that he must sleep with each wife on a bed made of different materials.

So he went hunting. First, he speared a buffalo. Then he speared a bear. Finally, he speared a hippopotamus. He skinned them all and took their skins home to make beds for each of his wives.

The following year, lo and behold! For the wife who slept on the bed made of the buffalo fur had a male child! And so did the wife who slept on the fur of the bear! But the wife who slept on the fur of the hippopotamus had TWO male children!

The chief asked the medicine man, "My first two wives each had a boy, but the third one had two boys. Why is that?"

"That's the way it always works," the wise old mage told him.

"How can you be so sure...?"

"It's the Pythagorean theorem," he explained. "The squaw on the hippopotamus is always equal to the sons of the squaws on the other two hides!"
