There once was a pasty white Missionary from Nebraska working with an African tribe deep in the heart of the Congo. One day the tribe elder comes to him and says; "Luzayisu lumbebeba Malaba ya yinza muvimba ya baluve ya muntu CLICK CLICK unnnnggggghhhh" which of course translates to "My wife just had just a baby, and it's white. You're the only white man within hundreds of miles of here. You will explain."
The Missionary takes a deep breath, gulps, and says; "Well, some mysteries in nature just can't be explained except by our faith in the Lord. Look at that herd of goats in your pen, for example. All of them are white, except for that one black goat. The Lord is very mysterious, but I'm sure this is nothing to worry about."
After considering the Missionary's words very carefully, the wise tribe elder nods and says, "OK, I'll keep quiet about my white baby, if you keep quiet about that black goat."
