S5, E19: The Janitor sabotages J.D.'s video diary for his Mom - Markie Post "People's Court") guest stars -- After J.D. (Zach Braff) helps Turk (Donald Faison) and Carla (Judy Reyes) turn his old bedroom into a nursery for the baby, he gets the idea to strap a digital camera to his head so his mom can see life through his eyes. But the project is cut short when the Janitor (Neil Flynn) seizes an opportunity to shove J.D. out of the picture for a day. Meanwhile, when mistakes by the interns begin to reflect badly on her, Elliott (Sarah Chalke) cracks the whip on her charges and even resorts to using her mother Lilly (Markie Post) to lean on Keith (Travis Schuldt) for information about his peers. Later, Turk accuses Dr. Cox (John C. McGinley) of not being hip. Ken Jenkins also stars.
