Doug Murphy Quotes

Dr. Cox: Nobody hurts Carla and gets away with it.

Dr. Cox: Do you know what you've just done? You just lost all lap-dog privileges.
J.D.: Excuse me?
Dr. Cox: No more walkies, no more treats, no more following me around the hospital.
J.D.: I'm not your lap-dog.
Dr. Cox: Hey you, back there, what do we do with lap-dogs who can't behave in the house?
Doug: Make them stay outside?
Dr. Cox: That's right. You now have five seconds to get out of this room, otherwise I'm gonna start whacking you on the nose with this!
