A visitor being taken around a farm spots a pig with a wooden leg and bursts out laughing.
The farmer turns on him and berates him for mocking the poor animal
"Don't laugh at that pig - it save my life twice. Last year I was coming home having had too much to drink and I fell in the pond - like a shot it jumped in and pulled me out by the collar.
Then a few months later, my tractor overturned in the top field with me under it and that pig ran over, scraped the earth from underneath me and dragged me out - I was in hospital for a month and would have died if it hadn't saved me."
The visitor apologied profusely and asked, " But why has it got a wooden leg?"
"You don't eat an animal like that all in one go!"
