I heard/read a story somewhere once, where there was a statue somewhere of someone who’s better off not glorified. The statue was defaced regularly, and every time it was defaced, there’d be someone cleaning it up.

Over time the statue went on to look worse for wear until one day, the authorities decided it was better to remove and replace the statue.

It turned out the guy cleaning it up was always the same guy, who hated the subject of the statue with a passion, and alway used salt water to clean it, hoping to corrode & wear down the statue. Some people suspect he and the vandal were the same person.
