On a humorous note:
“In every chaos there is an order: A very good writer wrote a rather nice book. But there was no title to it yet. He asked his friend for suggestions. The friend asked him if there was either a drum or a guitar mentioned in the book, to which the author replied in the negative. The book then had the title: A story without drums and guitars.”
(Endre Szemerédi, slightly paraphrased)
