When Lipsky gives Wallace his book to read at the end of the film, Wallace is frustrated that Lipsky was allowed to choose his own cover art for a relatively unknown book. It is well known that David Foster Wallace had no say in the original cover art of "Infinite Jest" and hated what his publishers settled on. Aside from being a light hearted in-joke amongst fans of Wallace, this also provides irony to the story, providing a comedic payoff to Lipsky's envy of Wallace's success.
