There was this native-american chief - from a Plains tribe - I presume nomadic. At any rate, they lived in teepees.A chief could have more than one wife, and this guy had three. He decided they needed improved bedding, so he got them new animal hides.Wife no. 1 got a new buffalo hide. Easy, buffalo were roaming the plains.Wife no. 2 got bedding made from several lynx hides, stitched together (you could make a handbag out of one mountain-lion, but it's not enough for a blanket).Wife no. 3 presented a problem. So the chief got onto Amazon, and ordered a hippopotamus hide from Africa, which was delivered by drone a few hours later (yes, Amazon had faster drones in those days).The chief and his wives all slept in the same teepee; and in due course, all three wives became pregnant.The first wife gave birth to a son.The second wife also had a son.The third wife had two sons.The moral of that story is "The squaw on the hippopotamus is equal to the sons of the squaws on the other two hides".
