Mine originated in my mispent youth. I had ( her indoors would say still have ) a tendancy to be a serious tut and pull apart anything remotely mechanical to see how it works ( or just to see what the insides looked like ). I had less of a tendancy to reassemble them - though when I did I must say with pride that many a time I had left over parts but it still worked.

On those occassions when my Grandfather would confront me as to why exactly there was a disassembled lawnmower in the middle of the garage we developed a routine where I would deny all knowledge and he would always say "I see, Gremlins did it huh ?".

In my teens and early 20s that somehow stuck with me. Later on I used it a bit online but with the nz in place of ns as us Kiwis are an unimaginative lot so whenever we see a "ns" we just have to turn it into an "nz" ( as in New Zealand ).

I was one of those inquisitive sorts, too! Another common point is that my former motorcycle shop was called Underground Engine Werkz. It was the German "werk" I liked and borrowed from the band Kraftwerk, but I too, was lazy and went the "Z" route at the end.

I was an Aviation Ordnanceman for 23 years. About 12 years were working on the Phantom and also as an instructor on the ordnance equipment.
