Hahaha, mine was unplugging a none working fluorescent tube in a vc10 which was still plugged in one end and I will be blowed, it lit up when my hand crossed the other end terminals, it also threw me across the cabin lol.
The other was on nights unplugging the stores printer to plug into my PC and crashing the whole of the stores system.
I trust you carried on unplugging it and helped yourself to it.
