A professor is sent to darkest Africa to live with a
primitive tribe. He spends years with them, teaching
them reading, writing, math, and science.

One day the wife of the tribe's chief gives birth to a
white child. The members of the tribe are shocked, and
the chief pulls the professor aside and says, "Look
here! You're the only white man we've ever seen and
this woman gave birth to a white child. It doesn't
take a genius to figure out what happened!"

The professor replied, "Chief, you're mistaken. What
you have here is a natural occurrence... what we in
the civilized world call an albino! Look at that
field over there. All of the sheep are white except
for one black one. Nature does this on occasion."

The chief was silent for a moment, then said, "Tell you
what.
You don't say anything more about the sheep and I
won't say anything more about the baby".
