Plot summary
On his day off, J.D. gets called into work by Keith. It turns out that Dr. Cox told Keith to call J.D. to let him see what it feels like to be pestered over little things, as J.D. had done to Cox as an intern. Laverne 's gospel choir is also present, singing a song called "Payback is a Bitch". Elliot is basking in the warmth of being seen as an endocrinology expert by her interns. In reality, however, around the hospital she is hiding pages of notes and books with the answers on them.
Turk attempts to convince a family to take their brain-dead son off life support so the hospital can perform its first on-site heart transplant, in which Turk will be allowed to assist if he is successful in persuading the family. Meanwhile, Carla jumps at the opportunity to look after Dr. Cox's young son Jack.
However, the crew finds challenges awaiting them. J.D. just wants to head home and is constantly waylaid by requests for assistance. Elliot is forced to conduct a seminar with several endocrinology specialists. Turk's dishonesty with the coma patient's family damages his credibility. Carla can't stand having Jack around and begins to doubt if she's cut out to be a parent.
Eventually, all of J.D.'s friends discover they already had what they were looking for all along. Elliot finds that she has been unknowingly memorizing her notes and therefore already has the "brains" to go to the meeting. Turk, after being completely honest with the coma patient's parents, convinces them to pull the plug and learns the coma patient carried a donor card allowing the "heart" transplant. Carla learns from Dr. Cox that she'll feel different about her own child than she does other people's and will find the "courage" she needs. Later, as they put their skills to good use, J.D. is finally allowed to go home.
