I’m pretty sure that’s the main point of the joke, that the doctor was nuts for even offering him a splint when the Multiweapon Robo-tool arm was available.
A family was taking a Sunday drive in the country when they came upon a farmer walking his fence line followed by a three legged pig.
They stopped and the father asked the farmer about the pig.
The farmer said “Let me tell you about that pig, last year when the house caught fire in the middle of the night he busted down the door and came in and woke us all up”.
Then there was the time my youngest son was stuck up a tree, but I was too far away to hear his cries for help. That pig ran up to me and led me to where he was."
And, another time, my tractor tipped over and I was stuck under it. He grabbed hold of my belt and dragged me out, saving my life. -amazing. What a pig!
“Well, that is a miracle, but how come that pig only has 3 legs?” the man said quite annoyed at this point.
Well," said the farmer, “with a pig that special… you don’t eat him all at once.”
It obviously wasn’t because he didn’t have enough dough.
