Upon his visit to Santa Monica, Grandpa is under the impression that Jack is a successful surgeon/physician at Wilshire Memorial Hospital, where Terri works; Terri allows Jack to "play doctor" in the office of doctor friend, who was on vacation. When Grandpa Tripper gets set to visit the hospital where he's led to believe Jack works. Janet also tries to help Jack pull off the deception, which backfires when Mr. Furley, who was hoping to see the doctor who was on vacation about his back, exposes the roommates deception, laughingly when Grandpa Tripper asks if he was there to see the doctor, thinking it was his grandson by saying, "He's no doctor...he's just a fruitcake!!". All turns out well when Grandpa is just as willing to accept Jack the sometimes-employed Chef as he was the physician!
