The old farmer

One day there was a old farmer and his wife and they owned a horse and a carrige. So one day they went out on the pasture to do some work,and there riding along and all of a sudden the horse stops and starts eating grass, the old farmer gets off and walks up to the horse and says "Thats one" so they start back on the path and the horse stops and starts bucking,so the old farmer gets off, walks up to the horse and says thats two,so he gets back on and there riding down the path a little farther and the horse just stands there, the old farmer gets off walks up to the horse and says thats three, so he hits the horse upside the head with the 2x4 kills the horse dead. The old farmer gets back in the carrige and his wife says, what the hell did you do that for, you know that was are only horse, the old farmer looks and his wife and says "Thats One"
