HI Trish luv: Once in my checkered career, I was working as an elevator adjuster. My job was to use an Oscilloscope to check for voltage changes in both acceleration and deceleration in order to have a smooth, yet fast elevator It is a critical part of the final acceptance .
One day I was bored and my fellow adjuster, that was also setting up a another elevator near me, had been pulling off some things on me. As I watched him concentrating on his oscilloscope I had a stroke of genius. Down stairs, next door was a novelty shop. I remembered seeing one of those flat light flashers disc that you placed in the socket before screwing in the light bulb. This cased the light to turn on for a bit until the disc became hot, then turn off for a bit, and on.
So off I went, I bought one. When he left for a smoke, I put it into his Oscilloscopes power connection then reassembled it. I then concentrated on being nonchalant and concentrating on my work.
Shortly he returned, turned on his Oscilloscope, started the elevator remotely, then settled back to check the sequence. Suddenly he looked starled, reached forward and tapped his scope, about this time the flasher had heated up enough to disconnect the scope and the dying trace left weird lines all over the scope face. The flasher turned on again, and for a brief while all was normal, he relaxed, then it disconnected once more. He was looking extremely worried, and puzzled.
He redid all of his connections several times in perhaps 1/2 an hour, went through several cigarettes . bounced a screwdriver off of three walls in frustration, then he looked at me to ask for help, unfortunately I just couldn't keep a straight face any longer, so he realized that I had something to do with it.
It took him 15 minutes to find the flasher, he kept it in spite of my asking for it back, sniff, spoil sport. An hour or so later, I felt someone watching me and looking up saw him looking at me through a hole in the huge control panel. Naturally I jumped up and ran behind the panel to see what he was doing. He was just standing there with his hands in his pockets looking nonchalant. I then said, "OK, what did you do"? He innocently looked at me and said "Nothing , why"?
I just knew that he had done something in revenge, so spent the better part of a day going over the many thousands of multiple connections with no results. So I finally decided to run the Elevator, and disgustedly found that He had actually done 'nothing', he merely tricked me with simple psychology heheh
For this they were paying me premium plus double time ??
