A Minister was walking down the street when he came upon a group of about half a dozen young boys, standing around a dog. Concerned that they might be hurting it or planning to, he went over and asked what was going on. The boys told him that the dog was a stray, and they all wanted to take it home and make it their own, so they'd argued about it, then decided to have a contest. Whoever told the biggest and best lie would get to keep the dog.
The Minister was appalled. "You boys shouldn't be having a contest to tell lies!" he exclaimed, then launched into a long sermon against sinning, lying, cheating and generally being dishonest, starting with "Don't you know it's a sin to lie?" and finally ending with a description of how to live a virtuous, honest life, such as he himself did.
When he finished, there was dead silence for a minute, then the smallest boy gave a deep sigh and said, “Alright Minister, I guess the dog is yours."
