The episode begins with Dr. Kelso telling Dr. Cox that he is thinking about offering full body scans at the hospital, an idea to which Cox is morally opposed. Cox thinks Kelso finally listened to him about something, until he later sees an obviously unethical television commercial persuading people to get the full body scan. He goes outside and sees a billboard with the same purpose. Cox voices his frustration to Kelso and bets him that if one person gets the scan, he will kiss his ring. Mr. Corman, the hypochondriac, enters the hospital wanting the scan. Also, Turk's boss, Dr. Miller, explains how she is excited for Turk and Carla's wedding. Carla is stressed from planning the wedding, causing Turk to calm her down by allowing her to uninvite some people if necessary. Meanwhile, J.D. and Danni are obviously bored of each other's company at a friend dinner party. He decides to break up with her. When she leaves, Danni remarks that J.D. always wants what he can't have.
Cox unsuccessfully tries to talk Corman out of the full body scan. Cox then takes him to lunch to try to convince him not to do it and accidentally brings up the bet, causing Corman to storm off. Miller starts treating Turk miserably seemingly out of the blue. Carla explains that she uninvited her from the wedding. Also, Janitor catches J.D. admiring Elliot from afar. Elliot asks Sean to move in with her, inflaming J.D.'s jealousy. He tries to talk her out of it. Sean overhears them and privately tells J.D. to let them be.
Cox finally admits to Corman that he doesn't want him to be in needless pain; it's not about the bet. To prove it, he lies to Kelso that Corman already took the test, thus losing the bet. Turk finally accuses Carla of making the whole wedding about herself. He then finds out that televisions will be at the reception to watch the playoffs (something proving that some events of the wedding are catered to him too) so he forgives her. Turk allows Carla to decide Dr. Miller's invitation status, and she declines. Finally, J.D. ponders if Elliot is really the girl he is supposed to end up with, causing him to confess his feelings for her. Emotionally confused, she leaves. Elliot later breaks up with Sean and instead chooses to be with J.D. At that moment, J.D. realizes he doesn't like her anymore (Since he always wants what he can't have, once he has it, he doesn't want it anymore.).
