Hans im Glück

After completing his training, Hans received a lump of gold as a reward, with which he went out into the world. As the lump soon became too heavy for him on his journey, he exchanged the gold for a horse with which he rode on. But not for long and the horse threw him off. So he exchanged it for a leisurely cow. What will Hans have left after all his bartering?
