A minister told his congregation, “Next week I plan to preach about the sin of lying. To help you understand my sermon I want you all to read Mark 17.”

The following Sunday as he prepared to deliver his sermon the minister asked for a show of hands; he wanted to know how many had read Mark 17. Every hand went up.

The minister smiled and said, “Mark has only sixteen chapters, I will now proceed with my sermon on the sin of lying.”
