<P> Jordan and Dr. Cox are preparing to throw a party for their son Jack's first birthday . Dr. Cox advises J.D. not to attend the party because Jordan's sister Danni, with whom J.D. had recently broken up, is also coming . Also coming to the party is Jordan and Danni's brother Ben (Brendan Fraser), whose cancer has gone into remission; however he has failed to have routine screenings and Cox advises him to get checked out . </P> <P> Meanwhile, Turk and Carla clash over removing a mole from Turk's face and Carla taking Turk as her last name after they marry, and one of Ted's band members quits . J.D. is taking care of an elderly man with an irregular heartbeat when Dr. Cox instructs him to run tests on Ben while Cox runs an errand . Twenty minutes later, J.D. is called to resuscitate a patient who has gone into cardiac arrest . </P> <P> When Dr. Cox returns, J.D. hands him a chart and informs him that the patient died . Dr. Cox angrily blames J.D. and sends him home, despite Ben's efforts to convince Cox that it wasn't J.D.'s fault . Two days later, Cox has been at the hospital for sixty straight hours and it is apparent that Jordan is worried he won't show up for Jack's party later that day . Ben follows Cox around the hospital, apparently trying to convince him to go to his son's party . </P> <P> Meanwhile, Carla is busy annoying everyone as she is looking for advice: first she is upset because she doesn't know what to do to repay Turk for having his mole removed, but when he asks her to agree to take his name (hoping she would say no so he wouldn't have to have the surgery) she gladly accepts his terms . But after that she is angry that Turk is' forcing her' to take his name . She asks an annoyed Dr. Kelso for advice; he responds that she may end up missing the mole after it's gone, even though she thinks she hates it . She finally decides that Turk shouldn't have to have his mole removed, and Turk respects her wishes to keep her own last name . </P>
