J.D.: Anyway, know Mr. Marks? He said he doesn't have any family to be a kidney donor? But he's got a son. We gotta find this guy.
Dr. Cox: Look, Newbie, there are times a man wants to keep something to himself. Like, say, he's got a son. Or he's 29-years-old and keeps a journal with a unicorn drawn on the cover?
J.D.: Ah, that's a horse with a sword on his head, and he's there to guard my hopes and dreams.
Dr. Cox: Come on, if the guy didn't tell you about his son, I'm sure he had a pretty good reason. You know, you always do this you get too involved in your patients' lives. And just exactly how does that usually work out for ya?
[flashback to J.D. chained to a radiator:]
J.D.: Eventually someone's gonna miss me, Jerry! Oh, God, no.
[present:]
J.D.: He made me watch Everwood.
