When Elliot is talking to Denise about the immune-compromised girl, she is wearing a different stethoscope in the shot where she says "After all, it's her daughter" than in the very next shot where she says "So I decided not to talk to her."
The Janitor: Maybe I was never in The Fugitive.
In the season 3 episode "My Friend The Doctor", we see that the Janitor had a small part in that movie. In real life, Neil Flynn (the actor that plays him) had it.
"Guy Love" by Zach Braff and Donald Faison (J.D. and Turk hug). This song is sung by J.D. and Turk in the season six episode "My Musical".
"Torn Blue Foam Couch" by Grand Archives (Closing scenes)
Elliot: Brianna should totally get to live her life, I'm gonna to talk to her mom... but you guys gotta do me a favor - she's really trying to get in my head with this whole "we're the same age" thing, so I'm just gonna start throwing out numbers, and you guys stop me whenever I get to the age you think I look like, okay? Twenty-two. Twenty-three. Twenty-four. Twenty-five. Twenty-five. Twenty-fi - you know, this is a really stupid game, okay? Aren't you guys late for some sketch show?
Denise: Crap. (Runs away)
Elliot: (Sighs) Idiots.
Denise: Anyone sitting here?
Sunny: Not just anyone. You.
Denise: Okay. No more talking till I'm drunk, okay.
Todd: I'm so proud of you, man. You know, I've always emulated you. I shave my privates bald to look like your head.
Turk: Todd! I'm actually kind of touched.
Carla: Listen, this place can make anyone crazy. Once, after a double shift, I swore I went home and crawled into bed with Turk. Next thing, I woke up in the on call room, spooning Dr. Beardface. Now the guy's always slipping me hotel keys.
Denise: (to Brianna's mother) As much as I hate to agree with Dr. ...
Denise: Your name is Sunny Day? (to Brianna's mother) Okay, as ridiculous as it was for her parents to name her that, I think what you're doing with Brianna is a thousand times worse.
Dr. Kelso: What do you want?
Janitor: I'm getting ready to torture Nurse Chest Whiskers.
Janitor: (to Carla) Head games aren't going to work on me. Unfortunately for you, I have a photographic memory. For instance, I arrived here yesterday at 7.45 a.m. At 7.50 a.m. I took a nap. At 2.45 p.m. I awoke to find you plucking a comically large hair off of your baby feeder. I then took my afternoon nap, then I went on break, and then I went home. Couldn't sleep a wink. Damnedest thing.
Janitor: (to Carla) Unfortunately for you, milady, I saw what I saw. You either plucked a giant hair, or you have mini chest snakes.
Turk: Cathy, you're playing Elliot. So I want to see some bug eyes, alright. And, perfect. Plus find some cardboard. Stick it down the back of your pants, right. Make that ass flat, girl, let me see what you got right now. Yeah, we can go flatter.
J.D.: We can go flatter.
Turk: We can go flatter.
J.D.: You know, I've chewed on that thing and it's flatter than day old beer.
Janitor: (to Carla) I think we should just get this out in the open. I saw you pluck your special hair the other day. I was there, I saw. Question is, what are we going to do about it? I have an idea. Let me speak first. May I? Good. I believe that you should give me the hair. Because I have been scrapbooking the most disgusting things that I could think of and I want to put it on the page in between my decayed molars and a snug, which is, a snail-slug hybrid that I was able to splice together in my garage. Unsuccessfully.
J.D.: Okay, well then let's cut the leukemia sketch.
Turk: Dude, no! That sketch is gold.
J.D.: Well if they're not naked, they're just sad and dying. What's funny about that?
Turk: You make them British.
J.D.: Good save. It's back in.
Elliot: You know, I used to use an incubator to keep my lunch warm. Until some whiny new mom complained that her premy smelt like a ham sandwich. Weird thing was, I had a tuna melt in there, not ham.
Denise: Okay, Mr. Rigo, I know you've been complaining about the bedpans being too cold, so I used an incubator in pediatrics to warm this bad boy up for you. Enjoy!
