Wyatt and Stiles are checking out some mice in a cage. Wyatt says that people are not mice, and Stiles goes on and on about all the ways in which mice make perfect research subjects for human medicine. Wyatt says, "When the cat's away, the mice will play." Stiles doesn't get that he's not talking about the mice in the cage anymore. Cherry comes in and points out that mice like cheese and people like cheese. How did this guy ever get a medical degree? Wyatt repeats that people are not mice.
Ben is talking to some guy, probably the Chief of Urology. That's what I'm going to assume, since they're discussing the results of Sonny's tests. Urology Chief confirms that Sonny has cancer, and surgery is the best option. He bases this diagnosis on "the art of the finger," which is really more information than I needed about Sonny's exam. Ben questions the surgery route, and asks about sexual function after surgery. Urology Chief explains that the studies define sexual function as "sufficient to achieve penetration" and likens it to "stuffing a pillow through a mail slot." Again, imagery I really didn't need. Ben doesn't know how he's supposed to advise Sonny about his options when the numbers are so vague. Urology Chief says that this is a common problem, but no one talks about it. Urology Chief also says that the wives tend to choose surgery, and the subsequent loss of sexual function, because they want their husbands around and the sex part "doesn't matter." Urology Chief cracks that sex "only makes the world go 'round," and walks off. Hey, I like Urology Chief. I hope he shows up again.
Sonny is out on the roof, and Cherry comes out for a smoke. Cherry approaches Sonny, saying he's "one of [Sonny's] biggest fans." Sonny bums a smoke from Cherry, after they both promise not to tell Ben. Cherry starts laying it on thick about Sonny's athletic career, and how much he admires him. Sonny keeps saying he wants to be alone, but Cherry's not getting it, until Sonny busts out with, "Pal, you are so far up my ass, you can't see your shoes." Ha! Cherry walks away, and Sonny apologizes. After some banter about flattery, Sonny tells Cherry that no one is supposed to know that Sonny is in the hospital, but Sonny has an MRI and he needs someone he can trust to answer his phone. Cherry is up for the job, so Sonny hands him the phone and his briefcase and takes off.
