Fat Tail Sheep

When I'm taking people out trail riding here in the Nile Valley, I usually have to answer a pretty funny question: "What's wrong with your sheep? What's that big thing hanging down behind?" The second question is often delivered in a tone of voice that indicates that the speaker isn't completely sure that they want to know. In fact, our sheep have these huge fat tails, quite ugly looking I think. But people here like them.
