The Monkey-minute. It is famously said that an infinite (or a large) number of monkeys typing randomly at a keyboard for eternity, will produce the complete works of Shakespeare (or some other literary canon). It follows, naturally, that for works of lesser magnitude or quality, a smaller number of monkeys (or shorter duration) will suffice. DilBert once asked Dogbert to assess the quality of poetry he had written; to which Dogbert repeated the above assertion. Dilbert asked "what about my poem?" Dogbert replies: "Three monkeys, 10 minutes". Hence, the monkey-minute is a measure of literary quality.
