Mine's boring, it just says Energy Efficiency Officer. I have been guilty of low tech alterations to a colleague's so it says "knobhead". trouble is, he didn't give it to the person I expected him to, thus spoiling my cunning plan.
I think if I really got to choose, it might be along the lines of Beer Testing Executive, or "eyelid internal surface inspector".
Kirst can't be that good at her job, she hasn't got round to me yet......
