Infinite Jest
The novel gets its name from "Hamlet", Act V, Scene 1, in which Hamlet holds the skull of the court jester, Yorick, and says, "Alas, poor Yorick! I knew him, Horatio: a fellow of infinite jest, of most excellent fancy: he hath borne me on his back a thousand times; and now, how abhorred in my imagination it is!" Wallace's working title for "Infinite Jest" was "A Failed Entertainment".
