The Irish Farmer's Pig

A salesman is lost in a rural area in Ireland and stops at a farm to
get directions. As he is talking to the farmer he notices a pig with a
wooden leg. "How did the pig get a wooden leg?", he asks the farmer.

"Well", says the farmer, "that is a very special pig. One night not
too long ago we had a fire start in the barn.
"Well, sir, that pig set up a great squealing that woke everyone,
and by the time we got there he had herded all the other animals out
of the barn and saved everyone of them."

"And that was when he hurt his leg?" asked the salesman.

"Oh no," says the farmer. "He was fine after that. Though a while
later I was in the woods out back and a bear attacked me. Well, sir,
that pig was near by and he came running and set on that bear and
chased him off.
Saved me for sure."

"So the bear injured his leg then," says the salesman.

"Oh no. He came away without a scratch from that. Though a few days
later my tractor turned over in a ditch and I was knocked unconscious.
Well, that pig dove into the ditch and pulled me out before I
drowned."

"So he hurt his leg then?" asks the salesman.

"Oh no," says the farmer.

"So how did he get the wooden leg?" the salesman asks.

"Well", the farmer tells him, "When you have a pig like that, you
don't want to eat him all at once."
