One of my favorite stories involves a newcomer to town who was standing in his neighbor’s yard when a three-legged pig came walking by.
“Why does that pig have only three legs?” the newcomer asked.
The neighbor explained: “Well, it’s like this. Late one night when we were all in the bed asleep, the house caught fire, and we’d have all been goners except for that pig. With no regard for his own safety or well-being, he broke down the front door, woke us all up, and got us out of the house alive.”
