Louis Guzman is a well-known Puerto Rican American actor who also is a Alumni of Greendale Community College. Due to his fame he was not only honored by the school by having a building named after him but also with a statue dedicated to him. His connection to Greendale was first mentioned in the Season One episode "Advanced Criminal Law" and his first actual appearance on the show was in the Season Three episode "Documentary Filmmaking: Redux". He is portrayed by himself.
During Craig Pelton's tenure as Dean of Greendale Community College he would often try to improve the school's reputation. Among the various plans he came up with to accomplish this goal was to take advantage of a famous celebrity who used to attend the college, character actor Luis Guzman. In the study groups first year Greendale, Dean Pelton first mentions the school's connection to the actor in a PA morning address. In it he announced the dedication ceremony of the Luis Guzman statue on the campus quad. The actor himself is not seen on school grounds until the study groups third year at Greendale. Dean Pelton was filming a new commercial for the college and Jeff , not wanting to participate, tries to stop the production. He lets Luis Guzman's lawyers know that his image (in the form of the statue dedicated to him) is being used illegally for the shoot.
It ends up having the opposite effect of what he had intended as Luis Guzman calls Dean Pelton personally (believing he's his predecessor Dean Carlton) to let him know that he's interested in appearing in the commercial. Luis Guzman arrives a few weeks later only to find the campus seemingly deserted. While walking the campus he is shocked to find the Guzman statue bearing his likeness on the quad. Eventually he makes his way to the administrations building where he finds a Dean Pelton along with Abed who is still filming his documentary of the commercial shoot. Pelton welcomes Luis and ushers him into his trashed office where he plays footage of the commercial. Luis is confused by the overproduced mess that he just witnessed and takes back his offer to participate. He is later interviewed by Abed for his documentary and implores him to help Dean Pelton who he believes has lost his mind.
The filming session is interrupted by Pelton's arrival who becomes angered that Guzman would work on Abed's pet project but won't do the commercial. After Pelton insults Luis for wanting to stick to the original script, the star suddenly realizes what's been driving the Dean's artistic madness: he is secretly ashamed of the school. Luis tells him that he loved his time at the school but it's not him or other graduates that Pelton should be idolizing. It's the people who are here now along with the school itself which he should be paying homage to. He adds that Greendale is a special place that changes people's lives and the Dean's actions have shown him to be unworthy of the school. he then leaves the campus as Pelton considers what he just told him.
