A man visits a farm and sees a 3-legged pig in the yard. He says to the farmer, "i see you have a 3-legged pig there".

FARMER: "Aye, I'll tell you about that pig. Last year my youngest girl fell into the duck pond. No one was about and she couldn't swim. The pig jumped out of his pen, ran across the yard, dragged her out of the pond and then came squealing at the kitchen door to alert me wife."

VISITOR: "But he's only got 3 legs ..."

FARMER: "Oi'll tell you what else; my youngest lad strayed out of the yard, onto the busy main road. A truck was bearing down on her. Oi was too far away to do owt. The pig, quick as a flash streaked across the yard and knocked her out the way, just before the truck hit her."

VISITOR: "But why has he only got 3 legs? ..."

FARMER: "Aye, that's a foin pig. He came and alerted us when me proize heffer was in trouble delivering a large bullock ..."

VISITOR: "YES, but how come he's only got 3 legs?"

FARMER: "Oh, well, if you've got a great pig like that you don't wanna go and eat it all at once!"
