A priest told his parish one day "Next week Im going to give a sermon on the sin of lying. To help you understand my sermon, I want all of you to go home, pull out your bible and read Mark chapter 17."
The next Sunday, after reading the Gospel and making the announcements, the priest asked for a show of hands. He wanted to know how many poeple read Mark 17. Every hand in the parish went up. The priest said, "There's only 16 chapters in the book of Mark. I will now proceed with my sermon on lying."
