It's Aquaman's opening day. Initial box office projections, already "Titanic"-sized, get even higher after the East Coast numbers stream in, giving everyone hope that the film has a chance to pass "Spider-Man" as the biggest opening weekend in history. To avoid getting recognized, Vince and the boys decide to take in a showing in the Valley, but the heat sets off blackouts and unsure West Coast numbers. The bouncing box office receipts and the heat push everyone to the brink, so to unwind, the crew ends up crashing a high school party, where Vince gets to live out his "Almost Famous" fantasy. When Ari finally finds them - a drunken Vince celebrating on a rooftop - he breaks the big news: "Aquaman" is back on track to break the weekend box office record.

Now Ari acts all neurotic, having lost Vince as client, his wife drags him to yet another therapist, where he denies caring for any client. The boys realize they can't rally say no to Amanda just because she's too hot. After Ari admits being unable to fire blinded employee Rob Rubino, something he normally enjoys sadistically, his therapist recharges his mental energy. Amanda proposes her own surprising solution.
