J.D.: [v.o.] I guess after a while you just get used to Dr. Cox's rants.
Dr. Cox: And of course the lab tech is nowhere to be found, so I can't get that tox screen I was looking for. What do you say we write him a friendly note, shall we? "Dear incompetent dumb-ass." [pencil snaps]
J.D.: [v.o.] The truth is, Dr. Cox isn't really angry, he's just amusing himself.
[Dr. Cox knocks a computer monitor off the desk.]
J.D.: [v.o.] Maybe he's a little angry.
[Dr. Cox sweeps a bunch of vials and beakers off a counter]
J.D.: We didn't need those. So, all done?
[Dr. Cox picks up a stool and throws it through an internal window towards a bunch of nervous onlookers]
J.D.: He broke his pencil.
