The AG agent was making his annual visit to farmer Brown's place. While the two were talking, a pig walked around the corner and the agent noticed the pig was missing one entire back leg. "What's the story on the pig?" the agent asked. "Ah" says the farmer, " back in the winter our house caught fire during the night and, that pig ran around and around the house squealing. He did that until he woke us and saw that we were all out of the house. Saved our lives, he did." "Wow" says the agent. And he lost his leg in the fire?" "Oh no" says Farmer Brown, "but he did save our lives and we figured it would be a shame to eat a pig like that all at once."
