A biologist, a statistician and a computer scientist are all riding a train together through Africa, when they notice a herd of zebra from their window. The biologist notices that one of the zebra are entirely white, and exclaims, "Wow! Look at that – it’s a completely white zebra! This is an incredible scientific discovery!" The statistician then responds, "Well, it’s only one zebra out of millions – it’s statistically insignificant." The computer scientist then sadly laments, "Oh no! A special case!"
