So, here at the office, we had to get a key lock on the womans restroom. (Men that had been using it were leaving nastiness that we just didn't feel like dealing with anymore). Anyway.....currently, the key is hooked with a paperclip and hung on the wall with a thumb tack. I'm trying to think of a cute or funny saying to laminate and use as the key chain. For instance, "Take this Key, when you gotta Pee." .
