A salesman is traveling through the countryside when his satnav breaks down. He decides he well and truly is lost so he calls at a farmhouse to ask directions.
The salesman knocks at the door of the farmhouse and while he is waiting for an answer he sees a three-legged pig limping about the farmyard. He thinks poor pig it must have got itself caught in some farmyard machinery. When the farmer comes to the door, he is only too happy to give the salesman direction.
After giving the salesman directions, the farmer sees the salesman looking at the three-legged pig and says: "Ooh arr, I see thee looking at the pig. He is a great pig and no mistaking. I will tell thee the story of that there pig".
The salesman looks interested and the farmer continues: "The wife and me were in bed and we hear pig scraping at the door. I tells the wife that there pig will have to go if he cannot behave itself. We hear the pig again and I throw a shoe at the door and shouts at the pig for creating such a disturbance. After getting back to our sleep, then weren't were woken up just before the cock crows by the Fire Brigade and there wasn't the house on fire? Well we had some luck and no mistake. Well didn't pig raise the alarm? Didn't he get on that there telephone contraption and get fire brigade out and save us from certain death? Marvellous is that pig. Best in the world. Saved me and the missus from an early grave".
The salesman is impressed with the story and marvels, along with the farmer, at the abilities of the pig and is touched by the love the pig must have for the farmer and his good wife. Then he asks the farmer "I hope you do not mind me asking something about the pig" The farmer says "No young fella, you go ahead". The salesman asks "why has the pig got three legs?". The farmer says "Ooh arr, with a pig as good as that, thee don't want to eat it all at once"
