That's One Mean Dog

One who had a very mean looking Doberman insisted that his was the meanest and that it could lick any other dog in the county. The second just looked at his mangy old yellow dog and said that he would wager his against any dog in the country. Well after some animated discussion they finally decided to let the dogs fight it out.

After a very short snarling match the old yellow dog leaps on the Doberman and kills it outright. The first farmer was aghast. His dog had been beating other dogs for years and had never had more than a small scratch or two. He turns to the other farmer and asks "What kind of dog did you say that was?"

The first farmer replies "Well before he lost his tail we called him a Mountain Lion!"
