Unknowing madshitter

Sometimes, the mad shitter manifests in people who don't even know they are doing the work of the mad shitter.

Here's an anecdote from "Acid Rain" that I found on the keenspot.com forums:

This guy I used to work with came up with this imaginary person we dubbed the "Mad Shitter". He plugged the all the toilets in our building. The guy I worked with, would come back to the office angry and complaining about all the stalls being disabled. Then he quit and admitted it was him all along. The running joke now if that there is no toilet he can't plug. He came back to work here at a different building and is plugging the toilets over there. He doesn't even do it on purpose.

I think pretty much every office has someone like this.

At my current job, we had problems with people not flushing, leaving toilet paper all over the floor. After a couple of complaints HR put up these signs saying "Flush the toilet, wash your hands, etc etc" Comically enough the signs worked and the disgustingness level dropped.
