　　格林童話：萬事通大夫(中英)

　　Doctor Know-All

　　Jacob and Wilhelm Grimm

　　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."

　　"What do I have to do?" asked the peasant.

　　First of all, buy yourself an ABC-book, one that has a picture of a rooster up front. Second, sell your wagon and your two oxen and buy yourself some clothing and other things that doctors use. Third, have yourself a sign painted with the words 'I am Doctor Know-All' and nail it above the door to your house."

　　The peasant did everything he was told to do. After he had doctored a little —— but not very much —— some money was stolen from a great and wealthy nobleman. Someone told him about the Doctor Know-All who lived in such and such a village, and who must know where the money had gone. So the nobleman had his carriage hitched up, rode out to the village, and asked him if he were Doctor Know-All.

　　"Yes, that I am."

　　"Then you must come with me and recover my stolen money."
