Re: One, OK, hundred, I have my doubts
As for the "dumb secretaries" part, I believe it's mainly because secretaries of the era were no better or worse than the average person when it came to computer literacy, but they were some of the first to receive PCs for work due to the nature of their jobs. Hence, lots of old stories about secretaries being poor with computers.
I met someone who claimed to have had the secretary that was the source for the following Essex girl joke:
How do you know if your secretary is an Essex girl? Because of the Tippex on the monitor!
She'd apparantly missed the training/familiarisation day for the "new fangled electronic typewriters".
