Pierce and Abed were two study group members who interacted the least. Pierce was confused by Abed's constant pop culture and meta references. Pierce often mocked Abed's eccentricities and would pronounce his name as "Ay-bad". Like the rest of the study group, Abed tolerated Pierce's comments and didn't take them seriously. Abed also understood that a part of Pierce's treatment of him was the fact he was jealous of his friendship with Troy. Pierce and Abed's first appearance together was in the Season One episode "Pilot". Pierce was portrayed by Chevy Chase and Abed is portrayed by Danny Pudi.
Abed Nadir was invited by his fellow classmate Britta Perry to a Spanish study group. He in turn invited Pierce Hawthorne along with several other members of their class to attend as well. Once everyone met up in the study room, Pierce took it upon himself to handle the introductions. He got everyone but Shirley's name wrong and mispronounced Abed's name referring to him as "Ay-bad the Arab". Individually they both went to great lengths to become Jeff's friend. Eventually Abed became closer to Troy while Pierce grew resentful of Jeff's constant rejection. On Halloween, Abed saved both Pierce and Jeff from a collapsing desk fort. Along with the rest of study group Pierce helped Abed try to woo a fellow student named Jenny Adams. He also went to a "Kickpuncher" movie viewing party and failed to amuse the other guests with his commentary. When Abed created a Chicken Finger mafia he had Pierce bribe Dean Pelton to protect their distribution network of the popular food item. During the annual paintball contest Pierce forgoes his alliance with Star-Burns to join Jeff, Troy and Abed's group. At the end of the school year, Pierce attended a keg party thrown by Abed in his dorm room.
