"In preparation for my sermon next week, I want you all to read Mark chapter 17. You are dismissed." So next week everybody comes back to church. After singing a few hymns, the pastor comes to the pulpit.

"How many read Mark chapter 17 like I said last week?" Everyone raised their hand. The pastor says "and it's a great chapter, amen??" There are shouts of "amen!" from the congregation. Then the pastor smirks.

"Well, Mark only has 16 chapters. I will now begin my sermon on the terrible sin of lying."
