Sudsmaster, how can anyone reason with such extraordinary reasoning. Are you sure it was only because the 'furrows' alluded to work? I would have thought that the 'furrow' could also have eluded to the female anatomy. A rudimentary and lustful depiction of that special place between a woman's thighs perhaps? What if the floor wasn't made of dirt and the chair left a skid mark? What depiction could that have alluded to?
