A tribal leader finds that his wife has had a white baby. Enraged, he brings the baby to the missionary at the tribe and says, "You are the only white man to inhabit our land. Explain to me how my baby is white." Terrified, missionary responds, "Now, now..please do not make any hasty assumptions. Look at those white sheep over there? Among them there is one black one. There is no explanation as to how it got that color and is just a miracle of nature." The tribe leader pauses for a second, then says, "I apologize, sir. I understand you well and clear. I'll keep quiet about the baby if you keep quiet about the sheep."
