Dr. Wen was not featured on the show after Season 6, but in Season 8, his name was seen on Dr. Cox's "Sometimes Allowed" list, and he was parodied in the annual interns' Sketch show. J.D. commented that the Dr. Wen Sketch was not working, referring to Dr. Wen's lack of comedic flair. When Carla became a surgical nurse, revealing things about Turk in surgery, Dr. Wen was seen laughing with the Todd under his mask. He made an appearance in the series finale. The character has the same name as a former writing partner of series Writer Bill Callahan; the two previously wrote for Spin City, which was co-created by Scrubs creator Bill Lawrence. Callahan and Wen parted ways in 2003 while working on 8 Simple Rules, a year before Callahan joined the show's writing staff. In "My Catalyst," his nametag said Phillip Wen.

Jimmy, played by Taran Killam, was introduced in Season 8. He was known at Sacred Heart as "the Overly Touchy Orderly" because he appeared to have an extreme tactile addiction — touching everyone and offering rubs, massages, or just general physical contact, regardless of whether people consented or not. However, J.D. stated that Jimmy successfully controlled part of his habit by touching people only above the waist. Jimmy's love for contact extended beyond people; for Example, when he was forced to keep his hands to himself, he fondled a table. He was temporarily part of the Janitor's "Brain Trust." He was fired by Doctor Maddox, only to be reinstated when she was removed as chief of Medicine. He had a talent for impersonation. He was seen in J.D's last fantasy at Sacred Heart, massaging Dr. Beardfacé.

He has an Oedipus complex regarding his mother, with whom he lives. He sleeps in the same bed as her and has remarked that she has installed a camera in the bathroom to check up on him when he bathes. In one episode it is suggested that Ted’s mother believes he is a Doctor, as he is shown coming home in stolen scrubs, claiming to have saved a patient’s life. Ted leads an a cappella group with three other non-medical hospital employees he calls his "Worthless Peons" (played by The Blanks, the real-life band of Sam Lloyd), and is shown to be uncharacteristically confident when surrounded by his bandmates. He also participates in biking and triathlons, often training with Doug Murphy. For one episode, he joins the Brain Trust with the Janitor, Todd, and Doug. He eventually becomes best friends with Keith Dudemeister. With the help of the Janitor and J.D., he finds the courage to ask Stephanie Gooch (Kate Micucci), a ukulele-playing musician who performs for the hospital's patients, on a date, and the two form a relationship and move in together.
