Okay.. this is something my Physics lecturer said.
There was an Indian Cheif, and he had three squaws. And kept them in
three tee-pees. When he would come home late from hunting, he would not
know which tee-pee contained which squaw.. being dark and all. He went
hunting one day, and killed a hippopotamus, a bear, and a buffalo. He
put the a hide from each animal into a different tee-pee, so that when
he came home late.. he could feel inside the tee-pee and he would know
which squaw was inside.
Well after about a year, all three squaws had children. The squaw
on the bear had a baby boy, the squaw on the buffalo hide had a baby
girl. But the squaw on the hippopotamus had a girl and a boy. So what is
the moral of the story?
The Squaw on the hippopotamus is equal to the sum of the squaws on the
other two hides.
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....
