I just found a switch next to the sink in the kitchen with just one word on it: "Press". No label to say what it is for or anything, just "Press". While part of me is screaming to press the button another part of me is a little more cautious.

Random switches could belong to anything. It might cause the end of all civilization as we know it. Perhaps it is a self-destruct for the building. Maybe it opens a secret entrance to another world. The possibilities are endless, and oh so exciting and scary, but the chances are it will just switch on the extractor fan. I think I'd rather not find out and leave it as a mystery.
