Did you know that in the House of Commons, there is a room especially built for the monarch to put on his or her robes before an official speech, and in that room there is a hidden toilet behind a panel and it is treason for anyone other than the reigning monarch to use it?
No, I didn't either until last week but it is AWESOME. Do you suppose there is a specially designated Robing Room Secret Toilet Cleaner? What would you put on your passport?
