Goof: When Abby and Carol are talking, Lucy brings in a patient in a wheelchair who throws up next to Abby's feet, but when Abby and Carol walk away and the camera pulls out, no vomit is seen on the floor.
Carol: Hey, Haleh, do we have any extra scrubs?
Haleh: I don't know and I don't care.
Carol: (to Abby) We really do get along.
Lucy: Somebody stole my patient...
Greene: Peter, did you steal Lucy's patient?
Benton: Check the lost and found.
Abby: Patients normally don't bite in OB.
Greene: That's an occupational hazard down here.
Romano: (to Peter) What's next? Liposuction for fat kids?
Malucci: ... My point exactly. It's coming out both ends.
Greene: Thanks for sharing, Dave.
Romano: Why mess with natural selection? Nothing like a good influenza epidemic to thin the herds.
Romano: Operating in the ER Peter? Shame on you!
Abby: (regarding Luka) Well, we never had doctors like that up in OB.
Haleh: Easy on the eyes, huh?
Abby: I'll say... Is he single?
Carol: You're a med student?
Abby: What can I say? I crossed over to the dark side.
Dr. Dave: I have a fever, feel my head.
Weaver: Feel your own head.
Carol: Residents - the only thing worse than med students.
Abby: I used to work in O.B., and up there I would deliver a baby, and then I would deliver a baby, and then I would deliver a baby. And today, I was puked on, spit at, bit, and then I tricked a psychotic woman, and then I almost killed a guy.
