Thus the whirligig of time brings in his revenges.

– William Shakespeare

Twelfth Night, Act 5, Scene 1. Feste’s reminder to Malvolio that what goes around comes around. Malvolio once complained to Olivia about the fool’s foolishness calling him a “barren rascal.” Now Feste, after taking on the role of a priest called in to cure Malvolio’s “madness,” has exacted his revenge on him.
