Abby's treating the nude old dude. He's standing with his back to the camera, gown flapping open to reveal Bare Geezer Ass -- droopy, a little wrinkly in unlikely places and a lot wrinkly in all the expected spots. It's Bea Arthur in derriere form. I'm not sure how this snuck through the censors. It's just the show using nudity for what it thinks is humor and shock. And the only reason it made it through, I'll wager, is that it's not Luka's bare ass blowing in the breeze. So basically, NBC and the FCC are saying that old person nudity doesn't count because it's not sexual, and that naked old people are -- pardon the pun -- nothing but the potential butt of a bad joke. (Like my Bea Arthur crack. Pardon the pun again.) That's really nice, NBC. Abby and Luka think that the Assman is suffering from nothing but worsening dementia.

Luka and Abby pedeconference their way into the hall. Luka asks interestedly about her graduation. "Eight short years later," she sighs self-deprecatingly. He wonders if her board results have come in yet; they haven't. She seems nervous. Malarkey calls out to Luka, and as he approaches, Abby is saying that she can walk in the ceremony, but won't get a diploma until she passes. "You haven't passed your boards yet?" Malarkey gapes. Abby pauses and almost bites off her lip in an effort to wound herself for her lack of volume control. She tries evading it by saying she took them last week; a clueless Malarkey is like, "Wow, I had to take mine six months before I graduated." Luka roughly leads him away before any more damage is done.

At the front desk, Frank is rudely telling a girl that she should go to the sixth floor if she wants Elizabeth, and he's using the kind of tone one would employ in the face of a child who has just somehow counted to five by way of twelve. "Rachel!" Jerry suddenly shouts. And we see that the girl with the curly updo is indeed that most infamous, genetically challenged demon spawn of Vulcan Jen and Zzzzzz, which is the nickname my brain gave to Mark Greene on account of the fact that it always shut itself off when he was on the screen. I will say that Rachel's hair looks nice up, and she's grown into her nose. "Jerry, how've you been?" she smiles. Jerry admires how she's grown, and then reminds Frank who she is. Frank's response is a classic "Oh."
