Simple - I give you a quotation, you say who it's by - Dostoevsky, Napoleon, Nietzsche or someone else. I've tried to be a little tricksy, but even if you get 0/20, some of the quotes should hopefully be worth the effort.
My second quiz. I've vaguely followed the categories from the first, so 'random' is now something of a misnomer. If you repeat something random enough times it becomes traditional - humans, eh?!
