I know these are called Romance Pants, but I can't imagine using them for anything other than coming home and turning the TV on and off without having to search for the remote before falling asleep (fully clothed, on the couch). Romance! It is alive and well at my house!
If you'd like to make this cybertronic clothing system a reality, Instructables has a whole guide on how you can create these pants and use them to do everything from turning your lights on and off to lighting candles. Unfortunately, these pants will not make you a pizza. (That is a dealbreaker.)
