BTW,
I must give credit to Tim Elms who actually drew that image, it came from an Electrolink magazine here from 1998.
He is an electrician from as he puts it "Pomgolia" who moved to NZ in the 1970's.
He has done a few articles (one of which Paul already has).
I will scan the rest of them and if you want a copy, by all means flick me an e-mail, these stories are quite funny.
