    I can't guarantee that this is the best approach, but I would write a
    small Perl program. If you don't mind duplicates in the output, read
    them into an array of strings then pick N items at random from the
    array. If you want to avoid duplicates, read them into a hash so you
    can delete each item as it is picked.
