Alex supposes that Cristina has some pretty kinky skeletons in her closets and Cristina tells him that the contents of her closets are none of his damn business. Izzie declares that she has no secrets because her life is boring. Would that be the secret about your former modeling career? Or the secret about your trailer park mother and her addiction to phone psychics? Mere says to her plate that everybody's got something to hide. She looks up and everyone's staring at her. Heh.

Burke enters Bill's room and tells him that he doesn't have a tumor. But he does have DNA from two different embryos that merged in the womb at the very early stages of development. In Bill's case, this means that he has a condition that produced gonadal hermaphroditism. Gesundheit. Bill's scared. "In English?" says Burke. "The mass in your bladder is an ovary." Bill's like, the huh? Burke says they're going to have an excellent gynecological surgeon remove it for him. Bill's still freaked out. Burke just assures him that it's a quirk of nature. Bill wants to know if he's still a man and if he'll have any sexual problems. Burke tells him he's a man's man, a Kappa man and then asks if they've been having any problems in the bedroom. "Was it my very pregnant wife that gave it away?" Bill quips. They both laugh and Burke tells him he won't miss the ovary when it's gone.

Ew. A needle. Alex is readying a shot of penicillin for George. "Are you sure you know what you're doing?" asks George. No, George. HE'S ONLY A DOCTOR. Alex just tells him it's a damn shot and that George is lucky he's even helping him out with this. "I've seen more of you than I ever wanted to. I'll be fighting nightmares for a week." George bends over the table and drops his pants so Alex can shoot him in the ass. The curtains open and it's Meredith. "Meredith! Go away!" George tries to shoo her out. "Oh, George," she clucks, "I thought you could use some moral support." Heh. George is all, NO! NO MORAL SUPPORT. NAKED BUTT! NAKED BUTT! Meredith just clucks some more at him, telling him it's not a big deal. "And you have a cute butt." Yeah, fat lot of good your cute butt comment does him NOW, Meredith. Alex whispers that he has a cute butt too, wanna see? "Oh, get out!" Mere snaps at him. "You're doing it wrong." George listens to all of this with his ass hanging out in the wind. Meredith moves in to take Alex's place with the needle and George is all, ALEX, WHERE ARE YOU GOING?? NAKED BUTT NAKED BUTT!!
