A missionary gets sent into deepest darkest Africa and spends years with the people, teaching them to read, write and good Christian ways. One thing he particularly stresses is the evils of sexual sin. Thou must not commit adultery or fornication!!
One day the wife of one of the Tribe’s noblemen gives birth to a white child. The village is shocked and the chief says “You taught us of the evils of sexual sin, yet here a black woman gives birth to a white child. You are the only white man who has ever set foot in our village. It doesn’t take a genius to work out what has been going on!”
The missionary replies says, “No, no, my good man. You are mistaken. What you have here is a natural occurrence – an albino. Look to the field. See a flock of white sheep, and yet amongst them is one black one. Nature does this on occasion.”
The chief pauses for a moment then says, “Tell you what, you don’t say anything about the sheep, I won’t say anything about the white kid.”
