A Pastor 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 Chapter 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 Pastor smiled and said,
"Mark has only sixteen chapters.
I will now proceed with my sermon on the sin of lying."
