To tell a lie

A minister noticed a group of boys standing around a small stray dog. “What are you doing, boys?”
“Telling lies,” said one of the boys. “The one who tells the biggest lie gets the dog.”
“Why, when I was your age,” the shocked minister said, “I never ever thought of telling a lie.”
The boys looked at one another, a little crestfallen. Finally one of them shrugged and said, “I guess he wins the dog.”
