Just some silly thoughts...
Since I and many others have chronic pain, does that mean the teapot would just keep going off and giving us money over and over again since our pain never goes away?
Would having surgery count as a pretty good way to make non-stop money without having to hurt yourself again, since surgery can be pretty painful and takes a long time to recover from?
I know it's fiction, but I always have to bring up silly points like this whenever they come to mind.
