     One day Nasreddin borrowed a pot (罐) from his neighbor Ali. The next day he brought it back with

another little pot inside. "That's not mine," said Ali. "Yes, it is." said Nasreddin. "While your pot was staying

receive two pots in return. However, days passed and Nasreddin had still not returned the pot. Finally Ali lost

"Died!" cried Ali, "How can a pot die?" "Well," said Nasreddin, "you believed me when I told you that your pot
