|Robert Laybourne was the vice dean of Greendale Community College and head of the school's air conditioning annex. Being in charge of the most profitable division of the college had made him a very intimidating and imposing figure. He ran the annex with an iron fist and personally recruited candidates for his school from Greendale's student body. He first appears in the Season Three episode "Biology 101". He is portrayed by actor John Goodman.|
|In the study group's third year at Greendale, Vice Dean Robert Laybourne was asked by Dean Pelton about the purchase of an expensive espresso machine for the Greendale Air Conditioning Repair School. Robert's response is to invite Pelton to his office to discuss the matter further. The next day Pelton arrives at Laynournes luxurious office and launched into a rant about his exorbitant spending. Robert explained that the AC school is the most profitable part of Greendale with alumni contributions responsible for 80% of the budget. Laybourne criticized Pelton for daring to question his purchases. He brought in his legal team to forge a new agreement between the schools and had his barber shave off Pelton's new goatee ("Biology 101").
|Robert's right hand man at the school, Murray, alerts him to Troy's impressive repair skills. He has Troy and other students kidnapped for a private "audition" to gauge their aptitude with air conditioning repair. When Troy easily fixed an air conditioning unit, Laybourne asks that he join him for a walk. He took him on tour of the school and related the history of air conditioning repair. After showing him the Room temperature room, Robert invited Troy to join the school. He gives him 24 hours to make his decision and warns him accepting the offer means leaving his old life behind. When Vice Dean later appeared to Troy for an answer he was turned down. Troy explained he'd rather spend time with his best friend Abed. Afterwards, Murray informs Laybourne Troy fixed an extremely difficult air conditioning problem in the cafeteria a few hours ago. Robert then became even more determined to get him to join the air conditioning school ("Advanced Gay").
|Laybourne is next seen sporting a goatee along with a ponytail. He approaches Troy again about joining the school, but this time, he tries another tactic. Seeing that Troy is unhappy that Abed does not want to pursue the Guinness Book of World Records for the world's largest blanket fort, he capitalizes on their disagreement as a means to create a rift in their friendship. It proves successful as Troy splits from Abed's pillow fort and tries to build his own blanket fort. In the end tag of the episode, Murray tells Laybourne that Troy and Abed are about to go to war over their competing creations. The vice dean is pleased with the news, hoping that a now-unencumbered Troy will finally join the air conditioning school ("Digital Exploration of Interior Design"). His plan ultimately fails, and in desperation, he turns to help from Dean Pelton. After a halfhearted attempt on his part, Pelton ends up being just as unsuccessful ("Origins of Vampire Mythology"). By the end of the year, very little progress was made in persuading Troy to join the A/C repair school; this changes after he and the study group get expelled. Troy contacts the school in order to save Dean Pelton whom they had previously learned from Chang's crony Dr. Heidi had been kidnapped and replaced with Faux-by. Murray supplies him with detailed information about the security layout along with an offer of assistance from the A/C school if he finally agrees to join.
|Troy seriously considers the offer when he sees the daunting task before him and his friends. Considering the price to be too high, the study group rejects the A/C school's help and instead goes ahead with an elaborate plan to infiltrate the school. However, the plan fails, and the study group along with Pelton are about to become victims of Chang's insanity. With his friends' lives at stake, Troy nods to a security camera used by the A/C repair school and accepts their previous offer. After they take down Chang, Troy reluctantly holds up his end of the bargain and enrols in the A/C repair annex. Murray personally picks Troy up and delivers him straight to Vice Dean Laybourne who is waiting for him with open arms ("First Chang Dynasty"). About a month later, Troy is attending class at the A/C school, but the loss of his friends causes him to be too distracted to pay attention to his studies. Hoping to shake him out of his stupor, Laybourne has Troy accompany him to a section of the school which houses historical relics from air conditioning's past. After showing Troy The Sun Chamber, he presents to him the Air Conditioning Repair Manual. Inside are sacred texts which detail the coming of an A/C messiah known as "The Truest Repairman".
|Laybourne tells him that he believes Troy to be the one foretold in the prophecy. Murray interrupts the vice dean's musings and tells him about an urgent repair that requires his expertise. Before leaving to take care of it, he reiterates his belief that Troy will become "the repairman who repairs man." Not long after, Troy sees a commotion in the hallway surrounded by a crowd of A/C students. It turns out Vice Dean Laybourne was killed after a freon line ruptured in what appeared to have been a freak accident. Troy confronts Murray about the accident, not believing that a veteran like Laybourne would make such a rookie mistake. When Murray reveals he has taken over Laybourne's duties as the vice dean, Troy becomes even more suspicious. Agitated by Troy's concerns, Murray cancels the debt Troy owes the air conditioning school and tells him he is free to go back to his friends. Troy initially decides to do just that, but as he is leaving the facility, a sudden blast of cold air in front of Laybourne's portrait strengthens his resolve to discover what really happened. He interrupts the coronation ceremony held for Murray who is about to assume control over the A/C repair school. In front of the attendees, he calls Murray's ascension a lie. Proclaiming himself to be "The Truest Repairman" and citing the sacred texts found in the Air Conditioning Repair Manual, Troy challenges Murray to a duel.
|They both enter The Sun Chamber as both compete to fix A/C units inside separate compartments while the heat inside steadily rises. With the the A/C faculty and students watching on, Troy easily defeats Murray in the competition. Frustrated by his loss and the unbearable heat inside the chamber, Murray accidentally reveals that he was responsible for Laybourne's death. Murray is about to succumb to heat exhaustion when Troy looks out into the audience and sees what appears to be an apparition of Vice Dean Laybourne. Inspired by the sight, he saves Murray by breaking through his portion of the chamber and fixing his air conditioning unit. He then stops the A/C crowd from exacting revenge on Murray by placing him in the Infinite Labyrinth of Eternal Ice. He tells them to take Murray to the police instead since he just confessed to murder.
