If you are ridiculously rich and can't find any other way to spend your money (please call me first), Murano House has developed timepieces that replace the plugs in your sinks. Sound nuts? I think so. Murano's "Watch Waste" (oh the possibilities with that one!) line of timepieces is available now, but you must email them for a price quote. Which means that they're probably worth more than my entire house. What better way to let your guests know that you should be stolen from than having one of these in your sink? A sign on the door would just be tacky.
