A farmer had some puppies he needed to sell. He painted a sign advertising the pups and set about nailing it to a post on the edge of his farm at the side of the road. As he was driving the last nail into the post, he felt a tug on his overalls. He looked down into the eyes of a little boy.
Mister," he said, "I want to buy one of your puppies." "Well," said the farmer, as he rubbed the sweat off the back of his neck, "these puppies come from fine parents and cost a good deal of money." The boy dropped his head for a moment. Then reaching deep into his pocket, he pulled out a handful of change and held it up to the farmer. "I've got 89p. Is that enough to take a look?" "Sure," said the farmer. And with that he let out a whistle, "Here, Dolly!" he called.
"I want that one," the little boy said, pointing to the runt. The farmer knelt down at the boy's side and said, "Son, you don't want that puppy. He will never be able to run and play with you like these other dogs would." With that the little boy stepped back from the fence, reached down, and began rolling up one leg of his trousers. In doing so he revealed a steel brace running down both sides of his leg attaching itself to a specially made shoe. Looking back up at the farmer, he said, "You see sir, I don't run too well myself, and he will need someone who understands."
