Perhaps you'll also believe me when I say I've read Infinite Jest too many times to warrant another reread right now, but best of luck on yours and the nascent book club, lol.
I think there are some less blink-and-you'll-miss-it type questions that are too broad to Google but that most people who read it would remember...
- Which location in ETA got its name from an infamous player?
- What fictional cartoon character is popular during Subsidized Time?
- What mortifying experience does Gately have in the hospital?
- What's Lyle's second-favorite beverage?
Or one that requires a longer reply and doesn't have a "correct" answer, but props to anyone who takes a stab at it, because I still don't have a satisfying explanation:
- What the fuck is wrong with Orin? Like in general?
