In the scene where Carla and Turk talk after rushing to the hospital, Turk's head moves noticeably between camera angle changes.
In this episode, the Janitor claims that he went to Yale. In the episode where this plot arc first appeared, My Lucky Night, the Janitor went to Harvard. (This is also confirmed as one of the Janitor's lies by J.D. in My Bright Idea.)
While The Janitor and Troy are trying to figure out J.D.'s riddle, behind them on the Patients Assignment Board there is a Dr. Booya and Dr. Mad.
When Body is carrying Elliot the third time she hits the door frame, you can clearly see that she does not hit it, yet there is a slamming sound.
When the bartender hands out the napkins, between the camera angle changes, all of the three napkins change positions four times without anyone even touching them.
When J.D. jumps of the ramp, he lands at least 6' away and it would take at least another 3' to break. How can his bike catch on fire when he landed so far away?
Dr. Cox: How about we just agree that we're never gonna be that close?
Elliot: We could, except for one thing. I know we have our issues, but I've always respected you, and you haven't given me more than an ounce of that since I started here.
Dr. Cox: ...I didn't go into that bathroom to take a leak. I went in there because I was petrified that I was gonna make the wrong decision about Mrs. Goldstein. And I didn't want anybody to know, because it is so very important to me that people see me the way they used to. Bulletproof. And hopefully admitting this to you will make you feel respected.
Dr. Cox: Barbie, are you a real doctor, or a doctor like Dr Pepper is a doctor?
J.D.: (Looking at his destroyed bicycle) What the hell?!
Janitor: (Holding a softball bat) It´s a riddle. Two guys destroyed your bike with a softball bat and a crowbar. One of them wasn´t me.
J.D.: Oh! That´s what happened to my old bike!
Dr. Kelso: Listen Reid, normally any damage to Dr. Cox's oversize ego would be cause for celebration. And yet, for some reason I'm not wearing a party hat sitting bare-ass on the hospital's copier machine. You know why? It's not because I have "Johnny" tattooed on my butt. He was an old navy buddy and if you went through what we did you'd understand... It's because your little theory is way off.
Troy: Oh, your face is red like a 'strawbrary'.
Janitor: Don't have kids.
Janitor: Hey, we solved your stupid game.
Troy: Yeah, we have been to the libary.
Janitor: ...'brary' Troy, library.
Turk: This is why the headache didn't go away, it is actually pronounced 'analgesic', not 'ANALgesic'. The pills go into your mouth.
Janitor: Okay, two coins equals 30 cents, no nickles. I swear, we've done this before...Come on man! You went to Yale, for god sake!
Troy: Relax...I figured it out.
Janitor: A penny and... a button that you wrote '29 cents' on. You think I don't recognize your hand writing?
Troy: Can't we just kill him?
Janitor: How's therapy going?
Patient: How was Acapulco?
Elliot: We told everyone that you were in Acapulco.
Dr. Cox: I never went to Acapulco. I lost three patients and spent the last two weeks on my couch trying to drink myself to death so that my victims and I could be reunited in the afterlife and they could rightly have their vengeance but then I realized that tactic would never work as I would be sent straight to hell, which I imagine is a lot like Acapulco only there would be fewer Latin men trying to sell me Chiclets on the beach. All the best.
Janitor: (To J.D.) Hey, come over here. We want to do stuff to you.
Hot Female Doctor: You know doctor, I'm getting a little tired of your sexual innuendo.
Todd: ...In your endo.
Dr. Cox: Nice helmet!
J.D.: Actually it is not a helmet, it is a 'hairmet'. You see, it's got extra room built in so you don't mess up your hair due.
Dr. Cox: I'm going to write you a prescription for two testicles. You get it filled whenever.
Elliot: I started an "I hate Cox" chat room. It didn't work out the way I planned. It's just me, two interns and 14,000 lesbians.
Carla: (She sees Turk holding a beer) What are you doing? (He threatens to open it) You better not open that. (He opens it) Okay, you better not drink it. (He takes a sip) All right, You better not enjoy it. (He expresses enjoyment, Carla bitch slaps his beer)
Turk: Did you just bitch slap my beer?
Carla: Are you calling me a bitch?
Turk: Yes. Yes, I am!
This episode was nominated for the 2007 ALMA Award for Outstanding Director - Television Series, Mini-Series, Television Movie.
Welcome Back, Kotter
The song the hospital staff is singing to Dr. Cox at his return is "Welcome Back, Kotter" which is the theme of the TV show Welcome Back, Kotter.
In the episode, Dr. Cox asks Elliot if she is a real doctor or if she is a doctor like Julius Erving is a doctor.
Julius Erving is a former professional basketball player who was well-known for his playing skills and for his nickname of "Dr. J."
The episode alludes to some of the most memorable moments in Scrubs:
The "hairmet", first seen in My Lucky Night. The ensuing scene is line-for-line a copy of that episode.
Nurse Martinez: Doctor, I'm getting a little tired of your sexual innuendo.
Todd: In your end-o.
This line first appeared in My Tormented Mentor, in which it ended up landing Todd in a sexual harassment forbidden
Dr. Kelso: Hey Champ, what has two thumbs and doesn't give a crap? Bob Kelso. How you doin'?
This is a recurring line for Dr. Kelso.
The storyline, in which the Janitor and Troy try to solve a riddle posed by J.D. first appeared in My Lucky Night.
Dr. Kelso: Dr. Reid, normally any damage to Dr. Cox's overforbidden
This line mirrors the one that appeared in My First Step, when he chewed out Carla for doing something only a doctor was authorized to do.
Turk: All right, this is why the headache didn't go away. It's pronounced annalgesic, not analgesic. The pills go in your mouth, all right?
This line was used in My Nightingale.
Elliot: J.D., not 'Floating Head Doctor'.
Turk: Elliot, save it. He's already gone.
First featured in My Big Bird, the "Floating Head Doctor" gag has gotten a little old by now, as evidenced by Elliot's comment.
Todd: Hey, I gotta run. They're doin' a breast reduction up on three, and I wanna get up there and stop it. You know what I'm talkin' about!
Todd used this line in the episode "His Story" (2x15).
Dr. Kelso: Son, do you not realize, that you're nothing more than a large pair of Scrubs to me?
This line was used in the pilot, when it was revealed that Kelso is actually a jerk.
Janitor: It's a riddle. Two guys destroyed your bike with a softball bat and a crowbar. One of 'em wasn't me.
J.D.: Oh, that's what happened to my old bike!
The same thing happened at the end of My Lucky Night. The difference in this episode is that in My Lucky Night, J.D.'s bike was destroyed by a crowbar and a baseball bat.
Dr. Cox not being able to make a decision and Elliot helping him alludes to My Old Lady, where Elliot had to make a decision and get Dr. Cox's help. Incidently, in both cases, the choice was whether or not to push thrombolitics.
The imaginary sequence, when J.D. finds an espresso machine under his future son's bed, is a send up of an anti-drug ad. The ad, which ran a few years ago, was part of a larger campaign themed around the idea, that parents who use drugs will have kids who use drugs.
Dr. Cox makes reference to the popular 20 year old actress and singer, Lindsay Lohan. She admitted in an interview to have an eating disorder.
