A man is travelling across the country and comes upon a field in which he spies a pig with a wooden leg.
This rouses his curiosity, so he pulls into the farmyard. He spots the farmer coming out of the barn, so he wanders over. "I just saw a pig with a wooden leg in that pen over yonder, and I was wonderin' how that came to be?"
The farmer replies "Why, this pig is really something else. One day, I got trapped under my tractor. My little fella ran on over to the neighbors and somehow got them to come on over and free me. This amazing pig saved my life!"
The traveler, amazed, says "That is amazing, so how'd he end up with a wooden leg?"
The farmer goes on to say, "Let me tell you about this marvelous pig. Another time, the house set fire and I was trapped inside, unconscious. This sweetheart of a pig ran through the flames, grabbed my arm in his mouth and dragged me out to safety. This little guy saved my life AGAIN!"
The traveler, mystified, replies, "That is a wondrous thing, but it still don't explain how the pig got that wooden leg."
The farmer goes on, saying, "Let me tell you...one time I fell in the pond, and not knowing how to swim, set to drowning. This beautiful creature dived on in, and pulled me out to safety, then gave me mouth to mouth resuscitation. The little bugger SAVED MY LIFE! AGAIN!"
The traveler, amazed, but now incredibly curious, asked again..."Wow, but..how'd he get the wooden leg?!"
The farmer replied, "A marvelous creature, I tells ya, a real beaut. A pig like that, you just can't eat a pig like that all to once!"
