>Sorry, but HHGTTG is one of my favourite works of fiction. Please forgive me for indulging my passion

Not at all, Max - you are quite correct, of course - it is a while since I read it, and my daughter has "borrowed" my copy, so I couldn't check. Anyone who cites HHGTG as a favourite book has to be a good and honest citizen, worthy of the respect of all.
The main thrust of my argument is not totally destroyed, I believe - although misquoting a source does tend to lose you marks.
