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 tribes 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! Youre the only white man weve ever seen
and this woman gave birth to a white child. It doesnt take a genius to
figure out what happened!
The professor replied, No, Chief. Youre mistaken. What you have
here is a natural occurrence, what we in the civilized world call an albino!
Look in 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
dont say anything more about the sheep and I wont say anything
more about the baby.
