Once upon a time, on the Holland family farm, there lived a pig called Percival.
Percival was a very special pig, and the Holland family held him in great affection.
One sunny, hot day in August, a visitor came to the farm. He was an old school friend of Farmer Holland and, as they had not seen each other in years, the two men embraced warmly. As I mentioned, it was a very hot day, so it would have been difficult for them to embrace any other way.
The farmer's friend - whose name was Peter - was given a tour of the farm, and it was then he encountered the very special pig, Percival, for the first time.
"That pig," said Peter, pointing at Percival. "He only has one eye and three legs. Moreover, I see his back is wreathed in bandages."
"Aha!" exclaimed the farmer. "That is Percival. He is a very special pig. Let me tell you all about him.
"Some years ago, my youngest daughter fell in the river, and he jumped into the flowing water, and pulled her to safety."
"That was a very special thing to do," said Peter, impressed.
"And not only that, but when we had a fire in the farmhouse, it was Percival that raised the alarm, and saved us all from perishing in our beds."
"Wow!" said Peter.
"And on yet another occasion, he scared away some burglars by leaping on them in the barn and emitting terrifying oinks."
"You must be so proud of him," said the visitor, and the farmer nodded.
"But tell me, why does he only have one eye and three legs? And why is his back swathed in bandages?"
"Ah," replied the farmer, touching the side of his nose with his finger. "A special pig like Percival, you do not eat him all at once."
