What if they list Tolkien books or have a forum nick from Lord of the Rings? By the way, 'Nazgul' and 'Narsil' aren't two words that would normally go together.
and those that list knuth or shakespeare are trying too hard ;-)
this is fun! you may not be able to judge a book by its cover, but I bet you can judge a person by their books (in a 'sufficient but not necessary' sense.)
