A traveling salesman was driving down a country road， coming upon a farm when he noticed a pig standing by the gate to the farm. Something was different about the pig and the salesman slowed down for a better look.
As he got closer he noticed that the pig had a wooden leg. It was intricately carved. Someone had taken a lot of time to make this leg for the pig.
The salesman decided to drive up to the farmhouse to find out more about the pig with the wooden leg. The farmer came out to meet him as he arrived at the house.
The salesman said， “I couldn't help but notice your pig with the wooden leg. What ever happened that caused him to have a wooden leg？”
The farmer said， “That pig is a special pig to us. Yes sir， he's really a special pig all right.”
The salesman asked， “What makes him such a special pig？”
The farmer explained， “Well， I guess he was just born that way， but that pig saved our lives. Our house caught on fire and that pig came up on the porch and banged and banged on the door and grunted and made such a ruckus that he woke us up. He saved our lives. He sure is a special pig to us.”
“I see，” said the salesman. “He sure is a special pig all right. I now can understand that， but how did he get the wooden leg？”
The farmer explains， “Now didn't I tell you that pig was a special pig？ Anyone knows that you don't eat a special pig like that all at once！”
