I do what I do the way I do it and that's pretty much it.— Janitor  ("Our Meeting in the Broom Closet") The Janitor was an unproductive custodian and handyman at Sacred Heart Hospital. He rarely actually performed the duties of his job, but rather spent his time plotting how to annoy J.D., on whom he performed many pranks. He was an avid liar, and nearly every story or anecdote he told people was a fabrication. He also led the Brain Trust group and seemed to be the leader of the custodial staff. Janitor was married to "Lady" Williams, but for a long time was infatuated by "Blonde Doctor" Elliot Reid. He competed with Dr. Cox at times, but his biggest competition was from Dr. Kelso, who often bothered him about not doing his job. He was afraid of Carla, but occasionally pranked Turk. Janitor was portrayed by Neil Flynn and appeared in 166 episodes of Scrubs as a main character for seven seasons. He first appeared in "My First Day" and was last seen in a flashback in "Our First Day of School," in which he simply walked out of the hospital after learning that J.D. was never returning to Sacred Heart.

Janitor's name, confirmed by series creator Bill Lawrence, is Glen Matthews. It is revealed in the Season Eight finale "My Finale". Janitor took great pleasure in making J.D.'s life as difficult as possible. vacuum cleaners stirchleyHe worked at Sacred Heart Hospital for 15 years, and in 2001, he revealed that he was 37 years old. numatic nqs250b vacuum cleanerHe claimed to have been working at the hospital for a "long time" and looked distraught and upset when Dr. Maddox fired him, but he ultimately scammed the hospital into giving him his job back. palson vacuum cleaner dubaiThe Janitor admittedly hated everybody. Very little about Janitor's family is known, because he told so many different stories about them, any of which be true.

He once joked that he was 's father. He had a whom other hospital staff members saw; however, he later claimed that his father had died before he was born. When J.D protested, saying he had met his father, the Janitor replied, "You met a man." Janitor claimed to have grown up believing that his mother was his sister and his father was his brother; he called them "sister-mom" and "brother-dad." He said that his mother once snapped her index finger because his dad was late to church and that when she dented the car, his dad threw himself down the stairs ("My Point of No Return"). He had a stepmother who was Inuit. He claimed to have a deaf sister and a brother who was a stripper. He also claimed that he had a stepbrother named Cleet who was older than his parents, hit a mid-life crisis, fought with his father constantly and slept with his mother. He claimed he was married to a woman with only a pointer finger on one hand and thumb/pinky on the other. He complained that J.D. made him miss his son's (named Timmy) school play by making him work , but later, he said that he did not have any children and didn't want any until medicine was advanced enough to make a child with gills, with whom he would go treasure hunting.

Janitor also claimed on several occasions to have gone to China and had a baby with a local. In one of J.D.'s fantasies, he appeared in his son's school room on Career Day, presenting himself as Dr. Ján Ïtor. After J.D. left Sacred Heart ("My Finale"), Janitor didn't initially believe it. He waited for him to return, but the next day, Turk confirmed to him that J.D. wasn't returning, and Janitor dropped his mop and left the hospital. Nobody heard from him again. ("Our First Day of School") Janitor was a wonderful liar and story teller, and could get nearly anyone to believe anything he said, even if they knew of his tendency toward dissembling. He fooled people into believing a variety of crazy stories, some of which turned out to be true. He proved that he was once a world-class 100-meter hurdler. Janitor often did things that didn't quite line up with the normal flow of Sacred Heart. He appeared in nearly every episode of Scrubs from Season One to Season Eight, and many strange subplots were dedicated to or driven by him.

Most of these were fueled by his vendetta against J.D. and his quest to prank him at every opportunity. Janitor frequently tormented all of the employees at the hospital, especially J.D. The two exceptions were Carla, whom he appeared to fear, and Elliot, whom he had a crush on. However, after the death of Laverne, he went to the bar along with other staff members and bought a round of drinks for everyone. Ever since the Janitor saw J.D. put a penny in a door, he devoted half his life to annoying him and playing pranks on him. He tormented J.D. daily, and took anything J.D. said to him as an insult about being nothing but a janitor. The Janitor also sometimes took it upon himself to give J.D. a reality check when he felt that J.D. was being smug, ("My New Game") ("My Jiggly Ball") ("My Identity Crisis"), claiming that J.D. "forces him to make his life miserable." ("My Own Worst Enemy") J.D. was Janitor's most common victim and was picked on by him nearly every day. Janitor understood J.D.'s profession and didn't get in the way of his job, but merely made things a little more difficult.

Despite this, the two shared some unusual bonding moments over the years. For example, after thinking he saw Janitor in The Fugitive, J.D. received confirmation that Janitor had acted in the film: He admitted that he wanted the actor to be the Janitor because it would make him more human and show that he had used to have dreams and ambitions, even if they didn't work out, rather than just being a jerk. Janitor also helped J.D get to Kim's ultrasound, although this could be the result of Janitor's falling out of a fast-moving vehicle. The Janitor was willing to put aside his rivalry with J.D. when it was in the interest of others, such as when they worked together to help Ted get a girl (though this alliance ended when Ted got the girl). He was also willing to be kind to J.D. on occasion, such as when J.D.'s father died. Janitor married Ladinia Williams, who was referred to as "Lady," the only exception being during their wedding ceremony, when the Justice of the Peace called her by her full name.

He wore sweaters, brought her flowers, and lied to her about his peculiarities. He tried to reveal who he was slowly so she would not freak out. They finally got married on vacation in the Bahamas, and she made him happy because she accepted him for who he really was. ("My Soul on Fire, Part 2") To the annoyance of J.D., Janitor was very nice to Elliot and often helped her out when she was in trouble. Elliot appreciated this and called him "sweet". Janitor called her "Blonde Doctor" because he didn't actually know her name. He learned her name once while on a date, but then continued to refer to her as "Blonde Doctor." He proposed to her, but she didn't notice. Janitor didn't often speak to Turk, but when he did, he treated him much as he did J.D. Although Janitor rarely spoke to Carla or any other nurses, he could often be found around the reception area with all the nurses, suggesting that he liked being in that area and with them. He did occasionally talk with Carla, however, and as with Elliot, he often helped her out.

He also found Carla very scary and rarely confronted her because of her rants, although he once tried to blackmail her into giving him her baby so he could sell it, and got the entire hospital staff to hate her after she refused to grant them favors on Kelso's behalf. In the custodial society of Sacred Heart, he was seen as a leader, and the other custodians seemed to obey his every command. He also often worked with other hospital employees, such as Troy, to annoy J.D. His original Brain Trust was composed of maintenance staff, but over the years, the membership changed. He rarely did his actual job, but the other cleaning staff never complained, presumably out of fear. Dr. Maddox didn't appreciate Janitor's pranks and began to question who he was. She asked him what his name was and got a very smug response. She then checked his name tag, and when she found it said "The Janitor," she fired him on the spot. When Dr. Cox was looking for ways to get Maddox fired, Janitor helped.
