"Sometimes we see a cloud that's dragonish,
A vapour sometimes like a bear or lion,
A towered citadel, a pendant rock,
A forked mountain, or blue promontory,
With trees upon't that nod unto the world,And mock our eyes with air.."
'The Answer to the Great Question... Of Life, the Universe and Everything... Is... Forty-two,' said Deep Thought, with infinite majesty and calm. — Douglas Adams, The Hitchhiker's Guide to the Galaxy
