S4, E8: Molly (guest star Heather Graham) announces to everyone that she's moving away for a new job opportunity, which stirs the waters of the triangle between herself, J.D. (Zach Braff) and Elliot (Sarah Chalke). When J.D. and Molly end up making-out at her going-away party, Elliot plays games with J.D. when he asks for her blessing for him to sleep with Molly before she leaves town. Meanwhile, Dr. Cox (John C. McGinley) has to fulfill community service hours and gets stuck riding around with a neurotic ambulance driver (guest star Molly Shannon) who drives him insane. Donald Faison, Judy Reyes and Ken Jenkins also star.
