The idiots around here are a special breed - the dumbest thing I ever heard a redneck say (being serious) was, “You cain’t fix it, if’n it ain’t broked.”
Well, I don’t think it is THAT dumb.
We have a saying in Engineering, “If it ain’t broke, don’t fix it.”
Not that far off from his.
The idea is you could make thinks worse or even break them in the process of trying to repair that which is working properly.
