In this episode J.D. is asked to introduce Dr. Kelso at an awards dinner, so he wants to find out something good about him. Meanwhile Dr. Kelso and Dr. Cox each have a patient, whom they feel deserves the benefit of a new experimental treatment, but there is only one open slot.
As chief of medicine Dr Kelso has to make some hard decisions and everyone at the hospital thinks of him as a jerk due to some of those decisions. At the beginning of the episode it shows how once Kelso leaves the hospital he begins whistling and appears to leave everything that happens behind him. Though at the end of the episode as Kelso is leaving the hospital you see that he in fact is upset by what he has to do, and when he see's J.D and others coming he quickly begins to whistle trying to appear unperturbed. A great episode and insight into Kelso.
