One of my first jobs, straight out of school, was in an electronics workshop. One of the radios were modifying for sale in Australia had some sort of of comparator network involving resistors of closely matched values. At the distance of nearly 40 years I can't remember exactly what it was for but I suspect it was in a PLL.

Every so often a big box of resistors would arrive and all hands would then calibrate their meters and start measuring and sorting resistors. At one point we had 200,000 resistors sorted into storage bins according to their measured value.

We had one chap, a bit of a practical joker, the type who would cut a length of 0.5mm tinned wire about 200mm long and piece it into the solder reel that hung above your bench just to watch you burn your fingers when the "solder" stopped melting...

One day old mate decided to super glue the bosses coffee cup to a shelf.

Later in the day, the boss grabbed his cup as he walked past. Unfortunately the shelf was a piece of plywood sitting on a couple of brackets. As the boss walked away with his cup the shelf followed, distributing the contents of the storage bins onto the floor.

200,000 resistors all mixed up again. Two days later we had them sorted into their bins again.

Old mate got a new nickname that afternoon: "Unemployed".
