You have to process a pig.
You realize you need a large metal basin to use to process the pig.
You tell your neighbor.
Your neighbor says he has a bathtub in his field that might do the trick.
(He was using it to water animals, but is no longer using it.)
He loads it up on his tractor.
And delivers it to your house.
And you go outside and see it in your driveway and think, "Man. That is perfect!"
