Two farmers, John and Henry, were sitting around talking about their day when John notices a pig with a wooden leg hobbling across the front yard. 

He turned to his friend and asks, "Henry, why does that pig have a wooden leg?"

"Well, John, that pig...," his eyes mist up, "That pig's mighty special! A few weeks back a wild boar attacked me while I was in the woods. That pig there came a runnin', went after that boar and fought him off. Saved my life!"

"And the boar tore up his leg?"

"No, just got a few scratches, nothing too serious. But that night the barn caught fire. That ol' pig started squealin' like he was stuck, woke us up, and before we got out here, the darn thing had herded the other animals out of the barn and saved them all!"

"Ahh so that's when he hurt his leg?"

"No, John, the next day my tractor hit a rock and rolled down the hill into the pond. I got knocked clean out. When I came to, that pig had dove into the pond and dragged me out...but that's not how he hurt his leg." "Oh no, no, he was fine. Cleaned him up real nice, too."

"Okay, Henry. So just tell me. How did he lose his leg?"

"Well", Henry begins to explain, "A pig that amazing...you don't want to eat it all at once."
