s02e06 My Big Brother

J.D.'s brother is in town. He came all the way from their hometown to pick up a car and drive it back for 300 dollars. His older brother is fun and easygoing, and quickly lays his charms on Elliot. J.D. tries to prevent anything from happening between them, and realizes that it's only because he's ashamed of his brother, who was the ‘the man' in high school and now is just a bartender living with his mother. When J.D. confronts him, he leaves. Meanwhile, Turk is thrown out of a patient's funeral for not knowing his name and feels even worse because earlier he made a bet with Dr. Cox over another patient's life. Dr. Cox later tells him that doctors make jokes and don't attend funerals because they can't get attached to the patients or else they won't stand the pressure.
