" A farmer walks with a potential investor when he sees a lovely sheep in the yard, except that he has a wooden leg. The buyer questions, "Why the wooden leg?" The farmer responds, "That sheep is so clever, I let it take the children to school." "Good, so why the wooden leg?" "The sheep is so wise it has a certificate in gardening and agriculture." "Incredible! But why the stupid wood leg?" "Well, once you have a sheep that clever, you would not eat it at once! "
