After much experimentation, Percy McKibbon discovered that it really is best to put the horse in front of the cart. To commemorate this momentous discovery, he took his wife and her maid to visit Stonehenge. Sadly, he forgot to set the brake, and he was run over by the horse and cart moments after this photograph was taken. His wife made no effort to publicize his discovery, and were it not for this lone piece of photographic evidence, the name Percy McKibbon would remain unknown. Not that it really mattered anyway, since everyone started driving cars shortly after the photograph was taken.
