One day the African chiefs wife gave birth to a white child and the chief was absolutely stunned. He suspected some hanky panky and went to the white Jesuit missionary father and looked at him suspiciously.

You have been fucking my wives, he accused the white father, who looked very uncomfortable. The Jesuit, tried to wriggle out of the difficult situation by trying to explain Mendels laws of genetics to the wrathful black.

You see that herd of sheep, he said pointing to the chiefs herd, Most of them are white; but you will also notice 2 black lambs among them.

OK! OK! said the chief. You keep your mouth shut and so will I.
