Late 80s early 90s I got into the database for our menus & recipes and changed ‘hot dog’ to ‘tibe steak smothered in underwear’ and then promptly forgot about it until one day months later with the storeroom clerk he was printing the monthly menus and inventory, lol and behold I laughed my ass off. He never even noticed because we just printed and filed the paperwork.

I also point around in areas that were ‘resteicted’ I found the ‘star wars’ game, and I would play it for hours on the midnight shift. Nothing like the old green screen games.
