X Marks the Spot
Not everyone was a fan of freely urinating in public. King Henry VII was so disgusted by the practice that he often had to paint large X's on the walls surrounding his garden to dissuade any "relief." It didn't work though, people just used the giant markings as a way to practice their aim.
Nude Cooking
Henry VIII must have had a truly disgusting castle because one of his other big issues was that his cooks never kept their clothes on. They loved to work completely in the nude. This was obviously unhygienic, even by olden standards, so a decree had to be made banning naked cooks.
