I moved to a new building at work, and one of the first emails that greeted me when I set up my computer was this gem: 
Hello Occupants,

We recently had a fecal contamination incident in the 1st floor men's room which will require special cleaning by the janitorial service.  This situation is disgusting and puts everyone who uses the restroom at risk. 

If you have an "incident", please request assistance in locating cleaning supplies so that you can clean up after yourself.  If you become aware of any such incidents, please report them to me or to your supervisor immediately.

If need be, the Criminal Investigator's office will be notified for appropriate action.

Thanks,
Building Manager
This is funny for a variety of reasons.  For one, as one of the building occupants pointed out, we're all adults.  We're old enough to take care of ourselves, and we all have enough experience controlling our bowels to get everything inside the toilet.  This kind of thing shouldn't be happening. 

Secondly, you can't pay for better fodder for conversation.  As my co-workers and I discussed it, we couldn't help but laugh like little children.  It doesn't matter how old you are.  Incidents involving feces are funny.  At an unrelated meeting later in the day, we discussed the incident at length.  Even old guys like project managers had a good laugh. 

Lastly, this isn't an isolated incident.  This is the third or fourth time it's happened in this building, and they apparently didn't catch the guy the first few times.  Even though it's gross and I feel incredibly bad for the poor folks who have to clean it up, here's to a few more fecal contamination incidents. #entertainment
