One day, Jesus and some of his disciples were walking in an alley when they came across a dead dog. The dog's body had been torn; it had rotted and the odor filled the air. Seeing this, the disciples started complaining about the smell, the sight of the corpse and how ugly the scene was. At that point, Jesus noticed that the dog had unusually bright and clean white teeth. He praised the teeth and pointed them out to his disciples.
