(Zach Braff) gets a lesson in competitiveness when he asks for Turk's (Donald Faison) support in persuading his patient to opt for medical treatment over surgery, and Elliot (Sarah Chalke) develops a crush on one of her patients (guest star Scott Foley, "Felicity"), but her own fumbling, insecurity and bad timing are compounded by their similar traits. Meanwhile, Dr. Kelso (Ken Jenkins) finds Dr. Cox's (John C. McGinley) Achilles heel when he fires the nurse who makes Cox's favorite cup of coffee. Judy Reyes also stars.

Hyde and Eric help Kelso break into the police academy to find out whether he is that year's fall guy. Fez must pass one final exam to become a U.S. citizen.

On J.D.'s last day at Sacred Heart Hospital, he finally settles his feud with the Janitor, tricks Dr. Cox into admitting their friendship and forecasts a happily-ever-after for the whole gang.

As Travis' downward spiral continues, Jules decides to give him some tough love; Andy and Lou Diamond Phillips give Laurie and Bobby advice on their new business.
