Janitor: Hey, idiot.  I said "idiot" and you looked
JD: I looked because you did the "hey idiot" thing to me, like, six months ago
Janitor: Did you look then?
JD: Yeah
Janitor: Heh
JD: You know what? I think you're out of ways to bother me
Janitor: No, you're wrong
JD: Think of a way to annoy me right now... That's what I thought
Janitor: You're stupid!
JD: See, now you're just embarrassing yourself. Pick someone else to annoy!
Janitor: I don't pick 'em. They pick me!
Dr. Kelso: Next contestant, Dr. Reid
Elliot: Mr. Murdock was admitted with a COPD exacerbation, he responded well to antibiotics and bronchial dilators but he did develop a rash on his, um.... private area
Dr. Kelso: Sorry, on his what?
Elliot: His peepers
Dr. Kelso: Excuse me?
Elliot: His schwing-schwong
Dr. Kelso: Dr. Reid, it's bad enough you run out on a patient in the middle of a pelvic exam. But you are a doctor, and you need to be able to say simple clinical words like "penis," or "vagina," or "anal"
Elliot: "Anal" is not a dirty word, sir
Dr. Kelso: Tell that to my wife.
Janitor: You know, loose debris can get sucked up into the air conditioning vents. And when that happens, I have to spend the entire day crawling around inside the wall, and I don't like that. You know why? 'Cause there's not enough air. I spent a day inside that wall thinking I was a mermaid. So here's the thing: you don't throw around loose trash, and I won't have to waste an entire workday granting the wishes of imaginary fisherman. 'Kay?
Cox: So, uh, there you are, superstar. Fix that
JD: Well, that's easy! Just tell her about it. Tell her everything you feel.
Cox: Should I give her every reason to accept that I'm for real?
JD: First of all, no one understands relationships like Billy Joel, okay? "Uptown Girl" got me through high school, long story for another day
Doug: Hey, Dr. Kelso, none of my patients have died today
Dr. Kelso: Really? Mr. Ferguson's corpse begs to differ
Doug: Darn it!
