S10, E7: To everyone's amazement, Lewis makes a date to share a home-cooked dinner with the elderly Ben Hollander (recurring guest star, Emmy Award winner Bob Newhart - "Newhart"), her depressed patient who is going blind. Lewis also treats a stressed housewife, makes plans to meet with the Internal Revenue Service for a tax audit and even finds time to hide Romano's prosthetic arm. Meanwhile, Neela and Pratt treat a vulnerable 18-year-old who was attacked in jail, and Gallant gambles with a risky hospital transfer to help a young septic cancer patient. Kovac clashes with Corday over the treatment of a patient who Corday suspects needs an appendectomy, and nurse Sam leaves her precocious son, Alex (recurring guest star Oliver Davis), in the emergency room--where the boy gets an advanced education in medicine--for a day.
