A sermon about lying
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."

A rabbi, a priest, and a lawyer were all...
A rabbi, a priest, and a lawyer were all caught in a shipwreck. Naturally, there are a lot of sharks circling around. All of a sudden, one shark darts in and grabs the priest for lunch. No more priest.
The rabbi starts praying frantically, but to no avail, as a shark comes in and eats him, too.

Now the lawyer is really worried, as a shark is coming for him. But, miracle of miracles, the shark puts him on its back, carries him to shore, and lets him off.

The lawyer, curious, waits till the shark is far enough away not to eat him, and asks, "How come you didnt eat me?" And the shark replies, "Professional Courtesy!"
