J.D.: You're late Keith. Which doesn't surprise me, because you're a terrible person.
Keith: Sorry, I was helping with a gunshot victim downstairs.
J.D.: Lies won't get you anywhere, Keith.
Keith: I'm... covered in his blood.
J.D.: That could be anyone's blood.
Carla: Here's the gunshot victim from downstairs.
Gunshot victim: Hey, my blood!
J.D.: That's not your blood.
Gunshot victim: Yes, it is!
J.D.: Quiet time.

J.D.: What guy drunkenly kissed you when you were sleeping?
J.D.'s narration: And it was at that moment that Turk and I remembered the incident we managed to block out for twelve years!
Turk: Uh, you're okay with us not hanging around for a couple of weeks?
J.D.: Totally!

Once when we were dating, Elliot asked me to urinate on her!

J.D. comes in, in pain
Keith: You ok, Dr. Dorian?
J.D.: Keith, it's like you're begging me to hate you.
Keith: I don't feel like I am.
J.D.: You can't stop, can you?

J.D. walks away with scratches on his back.
Jason: Dr. D, what's that on your back?
J.D.: Those Jason, are the panicked scratches of the adolescent raccoon, who until animal control can get into my home, is currently residing in my sock drawer.

A whole week of sleep, you're going to have some killer bed head. I'm nervous, I'm sorry. I love bed head, see?

Caveman bootycall
Cavewoman: Why you go now?
J.D.: Oh hey, you're up. Um, look, I don't know what you're looking for but I just got out of a really tough relationship with this girl, Debbie. Also, my sister was carried off by a giant bird so we've all been in mourning about that. And my brother ate my foot. But you are just fantastic. The things you were doing last night were well, crazy. Ok? So when I clear up my own stuff, I'd love to get back together with you.
Cavewoman: Hungry.
J.D.: Ok I should really go.

In J.D.'s room
Janitor: I come by here a couple times a week and move stuff around. Turn off his alarm. Maybe cut his bangs.
Dr. Cox: You're clearly in need of help but darn it, I'm not gonna give it to you. How sound a sleeper do you think he is?
Janitor: Well, watch this.
Janitor hits the bed and J.D. sits up then lies down again
J.D.: Why?

J.D. holds up a condom
Elliot: J.D., I can explain.
J.D.: (As he picks up another one) Oh you did it twice! Alrighty. Somebody's a stud. We got a stud alert here! (Makes a siren sound then picks up a bunch of condoms) Ok this is just mathematically impossible.

"El Toro Grande"? I'm not familiar with this brand.

J.D.: Your hero Keith here, forgot to check the blood levels on Mr. Joy this morning and guess what? He's dead. Way to go, Keith.
Keith: I've never even seen this guy before.
J.D.: Oh! Way to get to know your patients there, murderer.
Doug: There's Mr. Joy. J.D., did you steal him from the morgue?
J.D.: I left a note on the decapitated guy's stump that I'd have him back by 2. It's 1:45!

J.D.: Does anyone know what the cause of death may have been?
Keith: Maybe when you leaned over to check his I.V., you smothered him to death with one your love handles.
J.D.: What did you say, Keith?
Keith: Dr. Reid told me if you picked on me I should stand up for myself. And that you're very sensitive about your doughy physique.
