Many many years ago (when I was young and slender.....sigh) I worked for the Goodyear tyre company, back in the days before computers and copy machines when typists used carbon paper to make more than one copy. (Yes, I am that old.)
I was given a letter to type referencing the end-of-year shutdown when many employees took their annual holidays, to allow for factory machine maintenance. It was duly typed; I checked it, my boss checked it, his boss checked it, for all I know the Big Boss Upstairs checked it too.....and it still made its way to Akron, Ohio, with the heading "Christmas Shitdown", causing, I believe, great merriment on arrival.
