|Harry Jefferson is a very old, possibly the oldest, student at Greendale Community College. He is a stereotypical wise old man who likes to tell people stories in contrast to Leonard, who represents the grumpy, angry old man archetype. He also appears to have very limited vision. His first appearance was in the Season Three episode "Digital Exploration of Interior Design". He later makes a cameo in "Basic Lupine Urology". He is portrayed by actor Wil Garret.|
|In the study group's third year at Greendale, Britta witnesses a new student called "Subway" deliver a tray of tater-tots to an older student named Harry Jefferson in the cafeteria. Harry thanked him for his act of kindness but Subway modestly brushed it aside with humility. Subway praised Harry instead, claiming that although his eyesight was poor he saw things better than most people did ("Digital Exploration of Interior Design"). Harry is later seen discussing his time as a citizen of the "Pillowtown" fort in a documentary chronicling the infamous campus war with it's rival "Blanketsburg fort. Harry provides a first hand account of the conflict stating how much he enjoyed his time at Pillowtown ("Pillows and Blankets").
|Some time later, Harry is seen he taking part in an arm wrestling competition with Leonard in the cafeteria. This was done in front of a large gathering of other elderly students who were cheering them on. Pierce seemed to have organized the event as he was seen accepting bets on who would win. The contest was interrupted by Troy and Abed arrival, looking to talk to Pierce about the sabotage of their Biology project. The crowd quickly dispersed and Harry's opponent Leonard ran off with the other elderly students prematurely ending the competition. Harry was left behind still sitting in the booth either unable to follow or just not caring enough to bother trying ("Basic Lupine Urology").
