Scrubs:

When JD asks Dr. Cox to give the residents a pep talk, Dr. Cox takes things a little too far by telling them that inevitably, they will eventually kill a patient or two, which throws the staff into a frenzy. JD wonders whether he has ever specifically let someone die through his own incompetence and comes to the conclusion that he hasn't yet, though Dr. Cox is of the impression that it will happen eventually.

Meanwhile, Carla becomes so annoyed with Turk's stuffed dog Rowdy, she takes drastic measures to get rid of him. Elsewhere, Elliot fights for a patient who is an ex-drug addict to receive a heart valve, and becomes frustrated when Molly steps in to thwart her efforts.
