I do think that a PMS department is a great one cos I just go loony every month, and everyone around me, knows to staaaaay away! lol
I've told this story before, but hey - some of you won't have heard it yet.
Years ago, I had my own little company with offices in what had once been a nice old 3-bedroomed semi and was now a characterful 'office block'. My office was what would have been the 3rd bedroom; I kept the door open, always ready for anyone to come and chat, unless I was busy concentrating on something. Then the door would be shut but the team knew they should still knock and come in if there was anything needed discussion there and then.
One day I had all morning undisturbed. Now, this never happened, but I was grateful although slightly bemused. Until, that was, I returned to my office after going down to the kitchen to fetch a cup of coffee. Pinned to my door was a picture of a tiger, with the caption,
"I have PMS and a handgun. Now, what was the question?"
