That's kind of like the tourist driving along a rural road when he notices a pig with a prosthetic leg. He thought this unusual so he stopped at the owners house to ask about it. He found the owner and inquired about the story of the pig. The farmer said, "Mister, that pig saved our lives, my wife and I." There was a fire and we were asleep and that pig just kept squealing and oinkin' until we woke up and barely got out of the house alive!" The tourist was impressed and awed. He ask if the pig lost his leg in the fire. The farmer said, "Heck no, he made it out OK, and you know mister, you just can't eat a pig like that all at one time."
