Don't forget the ominous "Motor Stables" e.g., mil speak for routine/preventative maintenance.
As far as the Fallopian tubes, when I was still working in the OR, we used to tell the new scrub nurses/OR Techs we would need some for the next days surgeries. The whole hospital was in on the gag and would send them from one end to the other trying to find them. The smarter ones would realize what was going on after the second or third stop, others would be sent from the lab, maternity, CMS, OBGYN, ER, etc, etc. until someone finally let them in on the fun - kill joys!
