The missionary had brought his religion to the remote village in Africa and had sternly instructed the natives on the virtures of monogamy.

One day, however, a young wife gave birth to a white baby. The chief stormed into the missionary's hut. "You have taught us about the sanctity of marriage," the chief said, "and yet today N'Dawa gave birth to a white child. As you are the only white man here, the people say you are the father. They are very angry."

"Chief," the missionary replied, "the baby is not mine, it's an albino. See the black sheep there?" he said, pointing to a herd of otherwise white sheep. "It's a fluke of nature, something that just happens."

Shifting nervously from foot to foot, the chief cleared his throat. "Say no more, Father," he mumbled. "I won't tell them about N'Dawa if you won't tell them about the sheep."
