The Liars 说谎者
The minister announced that he would preach on the subject of liars next Sunday. He said, "To make preparation for my discourse（论述，演讲）, I hope you all read the seventeenth chapter of Mark."
On the following Sunday, when the minister began to preach, he said: "Now, if you have read the seventeenth chapter of Mark as I requested, please raise your hand." Almost everybody's hand went up.
Then the minister said: "I want to tell you that there is no seventeenth chapter of Mark."
