An ageing blacksmith realized he soon needed to retire so he picked out a strong young man to become his apprentice.
The old fellow was crabby and exacting. "Don't ask me a lot of questions," he told the boy. "Just do exactly what I tell you to do."
One day the old blacksmith took an iron out of the forge and laid it on the anvil.
"Get the hammer over there," he said. "When I nod my head, hit it real good and hard."
Now the town is looking for a new blacksmith.
