Jordan Sullivan Quotes

J.D.: Oh, thanks, that's-that's special. Look, I have to ask you a favor, but you have to know this is not why we slept together.
Jordan: Yeah, you had nothing to do with why we slept together.
J.D.: I think we both know that's not completely true.
Jordan: Oh, please. Even though you're terrified the Good Dr. Cox'll find out, if I wanted you to go to his apartment right now and have sex with me in front of him, you would.
J.D.: Please don't do that

Barbie, are you a real doctor, or a doctor like Dr Pepper is a doctor?

Dr. Cox

J.D.: Hey, I heard a great joke. A guy walks into a dentist's office and says, "I think I'm a moth." And the dentist says, "Well, if you think you're a moth, why are you at a dentist's office?"
J.D.'s narration: Oh, no, I forgot the punchline... You can't bail out now! Stall! Stall!
J.D.: ...So the moth says "That's a good question. What kind of dentist are you?" And the dentist says, "Well, I'm a general dentist, but I...I do dabble in orthodontry - braces and such." And... and the moth says, "Orthodontry? I hear there's great money in that."
J.D.'s narration: "The light was on"!
J.D.: "But! To answer your original question, which was, if I think I'm a moth, why am I in a dentist's office? The answer is, Because the light was on!" The light! The light, James. Moths love light. So, James, other than your funny bone being broken, what seems to be the problem?
