"A bass note sounds. It is a deep, vibrating chord that hints that the brass section may break in at any moment with a fanfare for the cosmos, because the scene is the blackness of deep space with a few stars glittering like the dandruff on the shoulders of God.
"Then it comes into view overhead, bigger than the biggest most unpleasantly-armed starcruiser in the imagination of a three-ring film-maker: a turtle, ten thousand miles long. It is Great A’Tuin, one of the rare astrochelonians from a universe where things are less as they are and more like people imagine them to be." - Terry Pratchett, Equal Rites.
