A Pig with a Wooden Leg

A salesman visiting a farm was amazed to see a pig walking round the yard with a wooden leg. He asked the farmer about it.
"That Pig is really the most wonderful pig that ever was.
One time I fell asleep in the barn and while I was asleep the barn caught  fire.Do you know the pig actually broker out of his pen ans came into the flame to drag me safety.
"That was certainly very impressive, but you have not told me why it's got a wooden leg."
"Well, a wonderful pig like that--you can just eat it all at once."
