Bathroom on the brain

Today one of the bathrooms in the library was "out of order". The bathroom was actually blocked off with a piece of caution tape, and if that wasn't enough to deter people, the customary "out of order" sign was also hung. For starters, I would never enter a bathroom that had a caution sticker. Granted, I always enter public restrooms with a certain element of ingrained "caution" (I mean truthfully, you never know what you are going to get), but if there is a sign cautioning me, it must be really awful--or at least that is what I think. 

A number of scenarios entered my mind trying to determine what could have happened that would have caused the closure. My juvenile mind immediately thought of gross things--that someone had...ahem...all over the bathroom. Come on admit it, you probably would have thought about it too, unless unlike me you have better things to do with your life than to wonder why a bathroom was closed--please, don't answer that thought, I'll just assume you do. But then I started to think of other reasons: logical ones, like there was a leak or something was broken; illogical, like there was a body in there (not logical because of the lack of police presence), and then it dawned on me that I will really find any excuse not to work on my final papers, even obsessing about bathroom closures. Are there any other possibilities you can think of for the bathroom closure? Fun times at the library, I know.
