The pranks in the maintenance shop were always a little more serious. Cars got shrink-wrapped. Tool boxes got placed in the ceiling by forklift, welded shut or were wired to an outlet. There was the high pressure hot water hose incident that almost got a few people fired, as well as the locker that got filled with instafoam through the vent. Unfortunately there was a nice leather jacket inside that took several hours to free.
Oh, and one very tempermental possum locked in the security truck on the late shift.
Shrink-wrapping an entire car? If I were wearing a hat, I’d take it off to the maintenance guys. That must have taken work!
