A young bull and an old bull stood atop a hill grazing some sweet sweet grass. By and by they spotted a herd of cows let into the pasture in the valley below them. The young bull pawed the ground with his hoof, snorted, and bellowed "let's run down the hill and service us one of those there cows!!!" The old bull continued to chew his cud thoughtfully. After a pause, he said "Nope. Let's walk down the hill and service them all."
