A good few years ago I was among a group of Royal Marine Reservists visiting the Dutch Marine corps in Rotterdam. We were often disciplined for the slightest misdeed (unlike the Dutch who were VERY laid back)and one of the tasks we were set as a punishment was polishing one of the two canon in the barracks foyer. Well we were disciplined quite often and we always (despite requests from the Dutch) polished the one gun. At the end of two weeks in Holland the Dutch were left with the task of bringing the second gun up to scratch.
