So this guy stops at a farm and sees a three legged pig.

So this guy stops at a farm and sees a three legged pig. He asks the farmer, "Why does that pig only have three legs?"

"That's no ordinary pig" answers the farmer. "Last year we had a fire in the barn. That pig opened the barn doors, herded out the cows, and then woke me up to call the fire department!"

"By why does he only have three legs?" continues the man.

"Then a few months later we had a prowler. That pig saw the prowler up on a ladder, knocked it down, tackled the prowler, ran and got my gun, then led me to the wounded intruder" continues the farmer".

"Ok it's an amazing pig, but why only three legs" the man persists.

"Then just the other week one of my grandkids was visiting and wandered off" continued the farmer when the stranger interrupted him "Look just tell me why the pig only has three legs!"

So the farmer looks back at him and says "well you don't eat a pig like that all at once."
