A guy is driving down a back road, looks over into a field and sees a pig with a wooden leg.
Unable to contain his curiosity, he drives up to the farmhouse where he sees a fellow sitting on the porch. "Excuse me," says the driver, "but I couldn't help but notice you have a pig with a wooden leg." "Yes," the farmer replies, "and I want to tell you he's some kind of pig. One time, one of the kids was trapped under a log down in the creek and the pig ran all the way here and led us back. If he hadn't, the kid would have drowned. Another time, my wife and I were asleep in our bedroom when a fire broke out. Pig knocked in the front door, ran up the stairs and pounded on our door until we got up and escaped. Yessir, I could tell you some other stories as well ... he's some kind of pig."
The driver looks at the farmer perplexed. "I can see he is some kind of pig, but that doesn't explain why he has a wooden leg."
"Oh that's simple," says the farmer: "A pig like that, you don't eat him all at once."
