Some authors have bent and twisted proverbs, creating anti-proverbs, for a variety of literary effects. For example, in the Harry Potter novels, J. K. Rowling reshapes a standard English proverb into "It's no good crying over spilt potion" and Dumbledore advises Harry not to "count your owls before they are delivered". In a slightly different use of reshaping proverbs, in the Aubrey–Maturin series of historical naval novels by Patrick O'Brian, Capt. Jack Aubrey humorously mangles and mis-splices proverbs, such as "Never count the bear's skin before it is hatched" and "There's a good deal to be said for making hay while the iron is hot." Earlier than O'Brian's Aubrey, Beatrice Grimshaw also used repeated splicings of proverbs in the mouth of an eccentric marquis to create a memorable character in "The Sorcerer's Stone", such as "The proof of the pudding sweeps clean" (p. 109) and "A stitch in time is as good as a mile" (p. 97).
