Here's a funny one. A scientist decides to go to Africa and study the native tribes. So he finds a tribe he likes and stays with them for awhile. One day the Chief's wife gives birth to a white baby. So the Chief goes up to the scientist and says "My wife just gave birth to a white baby. Seeing how you are the only white man I have ever seen, you must be the father." The scientist replies, "No, you see, this a natural occurence in nature. It's called an Albino." The scientist points at a herd of sheep. "See how that one sheep is black and all the other sheep are white." So the Chief replies, "If you don't tell anyone about the sheep I won't tell anyone about the baby."
