Doctor Know-All

Once upon a time there was a poor peasant by the name of Crab who drove two oxen with a load of wood into town where he sold it to a doctor for two thalers. He received his money just as the doctor was sitting down to eat. When the peasant saw how well the doctor ate and drank, his heart took a longing for the same things, and he decided that he would like to have been a doctor. He stood there for a while, and then asked if he too could not become a doctor.

"Certainly," said the doctor, "in no time at all."
