Dr. Cox: Never make assumptions based on your own perceptions. Just... never do it.
J.D.: Really? You've been spending a lot of time treating my guy, Mr. Jenkins, right?
Dr. Cox: Yeah, he's a Vietnam veteran, he deserves as much.
J.D.: Yeah, actually, he's just a homeless guy. I made up the war veteran story to motivate my boys! But, what're you gonna do?
(Cox starts flashing his "warning light.")
J.D.: Oh, come on! You've gotten me like a hundred times. I finally got ya once! It was bound to happen, right?
Dr. Cox: I see your point. Kindly blow it out your ass.
