Once upon a time there were three ladies of the First Peoples of America sitting around the campfire.
On a reindeer skin sat a lady who was the mother of a fine young warrior who weighed $140$ pounds.
On a buffalo skin sat a lady who was the mother of a fine young warrior who weighed $160$ pounds.
The third lady, as well she might, was sitting on the skin of a hippopotamus, as she herself weighed a mighty $300$ pounds.
As you can see:
- The squaw on the hippopotamus is equal to the sons of the squaws on the other two hides.
