Guy walks into a hotel A few years back, a feeder tournament for the World Series of Poker has attracted a lot of people to the town where it is being held, and every hotel in town is sold out. A guy without a reservation walks in and asks for a room. The desk clerk tells him “Sorry, but there are no rooms available. Due to an event in town, we have a full house”. Guy reaches into his pocket, pulls out a shiny metal object, and tosses it on the desk. Clerk looks at it, and it appears to be the lever from a toilet tank. On closer inspection, it’s engraved with a symbol containing the letters “E” and “R”, and the Roman number “II” - the Royal Cypher of Queen Elizabeth II. Guy tells the desk clerk “A Royal flush beats a full house, so give me the key to my room”.
