Once, many years ago, when a co-worker was on holidays we taped some newspaper loosely to the inside of the office facing window (picture the office door, then a thin maybe 6" across floor to ceiling window, then solid wall), then filled the space between the window and the newspaper with the styrofoam popcorn type balls up to about 6 and a half feet. We also jammed his door shut, and rigged it so when he tried to shove it open, a few more popcorn balls would fall out.
The net effect was that it appeared the entire office had been filled to the 6 and a half feet level with styrofoam balls.
He came back from holidays, walked up to his office, shook his head, turned around and left muttering "call me when my office is cleaned up".
Everyone was laughing so hard we couldn't get to him before he drove away, and we had to call him at home later and tell him to come back in...
Another one was related to golf balls. Even more years ago, I acquired a few golf balls from a driving range one late night. I never got rid of them, and they seemed to follow me around for years. Anyway, we would setup a binder on its side (which makes a great ramp) in some unsuspecting soul's overhead bin, use a clipboard (or one part of a binder, or a file folder, etc) to block the golf balls, close the lid, pull out the block and wait....... days later you'd hear the crash, followed by the swearing.
Important safety step though - make sure the balls aren't going to fall directly on breakable things, or computers... loud scary noises are funny, broken family heirlooms - not so much.
