I have 'worked' for Xerox for umpty ump years and someone who works for Xerox is a Xeroid.
But then I got redundanted, picked up by the company that does the outsource IT for Xerox so I became a Zeroid. Also a play on Zero ID ( no ID/name ).
The joke is I am still 'working' for Xerox ...
Over the years they have tried to get rid of me 3 x ... but I am still here Bwhahahahah
