How exactly do Monica and Phoebe constantly manage their way into Coma Guy's room? They mention that he doesn't have anyone, which they only could've found out by asking the ward staff.
And if they faked their way in by impersonating relatives, then wouldn't they have been given his belongings, including his wallet and ID, from which they could've gleaned where to find his next of kin, or at least his name?
Nora asks the despondent Ross out in the restaurant corridor if he knows how she's sold millions of copies of her romance novels, and he responds by guessing if it's the girl on the cover with her nipples showing. Given the demographic that presumably buys romance novels, wouldn't it make more sense to guess it's the guy on the cover with his nipples showing?
