Growing up my old neighbor, a licensed plumber, was one of the cheapest people I've ever come across. He had a ponton that was held together with the new coat of paint he put on it every year.
This thing was constantly springing new leaks, that he'd have to fix. Came home one day and he was standing in waste deep water with an electric grinder, grinding off the rust and 40 layers of paint so he could weld a patch.
His cheapness caused him to do some of the dumbest things I've ever seen. Yet he was able to die a natural death.
However, the subsequent owners of that house, which was also held together with paint and carpeting, were also as dumb as he was. to this day, we can't figure out if dumb people just bought that house, or if the house had some sort of evil spirit that made the people living there dumb.
