English Original
There was once a poor peasant named Crabb. He sold a load of wood to a doctor for two thalers. While receiving payment, he saw the doctor dining elegantly and wished to become a doctor himself.
He asked the doctor how to become one. The doctor told him to: 1) Buy an ABC book with a rooster on the cover; 2) Sell his cart and oxen to buy proper clothes and medical supplies; 3) Paint a sign saying "I am Doctor Knowall" and nail it above his door.
Crabb did as instructed. Soon after, a rich lord had money stolen and heard of Doctor Knowall. He fetched Crabb and his wife, Grethe, to his castle for dinner.
As the first servant brought a dish, Crabb nudged his wife and said, "Grethe, that was the first," meaning the first servant. The servant, who was the first thief, thought he'd been exposed and panicked. The same happened with the second and third servants.
The fourth servant brought a covered dish. The lord asked Crabb to guess its contents. Crabb, clueless, sighed, "Ah, poor Crabb." The lord exclaimed, "He knows who has the money!"
The terrified servants confessed to Crabb, offered to return the money plus a reward, and led him to its hiding place.
Satisfied, Crabb returned to the table, opened his ABC book, and pretended to search. A fifth servant hid in the stove to eavesdrop. Unable to find the rooster picture immediately, Crabb muttered, "I know you are there, so you had better show yourself." The hidden servant, thinking he was discovered, jumped out in terror, crying, "That man knows everything!"
Doctor Knowall revealed the money's location without naming the thieves. He received rewards from both the lord and the servants and became a renowned man.
中文翻译
从前有个名叫克拉布的贫穷农夫。他把一车木柴卖给一位医生，换得两泰勒。在收钱时，他看到医生优雅地用餐，便心生羡慕，也想成为一名医生。
他询问医生如何成为医生。医生告诉他：1) 买一本封面有公鸡的识字书；2) 卖掉他的车和牛，买些得体的衣服和医疗用品；3) 制作一块写着“我是无所不知的医生”的招牌，钉在门上。
克拉布照做了。不久，一位富有的领主丢了钱，听说了“无所不知的医生”的名号。他接上克拉布和他的妻子格雷特到城堡赴宴。
当第一个仆人端上菜时，克拉布碰了碰妻子说：“格雷特，这是第一个。”意思是第一个上菜的仆人。而这个仆人正是第一个小偷，他以为自己被揭穿了，惊慌失措。同样的情况发生在第二个和第三个仆人身上。
第四个仆人端上一个盖着的盘子。领主让克拉布猜里面是什么。克拉布毫无头绪，叹息道：“唉，可怜的克拉布。”领主却惊呼：“他知道谁拿了钱！”
吓坏了的仆人们向克拉布坦白，承诺归还钱财并额外酬谢他，然后带他去了藏钱的地方。
克拉布心满意足地回到餐桌，打开他的识字书，假装查找。第五个仆人躲在炉子里偷听。克拉布一时找不到书上的公鸡图片，咕哝道：“我知道你在那儿，你最好自己出来。”躲藏的仆人以为被发现了，惊恐地跳出来喊道：“这个人无所不知！”
“无所不知的医生”指出了钱藏在哪里，但没有说出小偷是谁。他从领主和仆人双方都得到了丰厚的酬金，从此成了名人。
