In this episode, Abed makes a documentary about Changnesia in order to receive a research grant, with Jeff attempting to prove Chang is faking his disease.
Dr. Ken Kedan (Marc Jablon) is studying the rare disease, described as affecting the memory, but not the ability to make forced puns.
After being chided by Shirley about second chances, Jeff outwardly complies with the group in order to continue to secretly undermine the documentary.
They, along with their cameraman, Garrett Lambert (Erik Charles Nielsen), interrogate a trout fisherman, Sully Sullivan (Mike Hagerty) who confesses to using Chang as unpaid labour for three months after seeing Chang emerge out of a trout tank, and named him Kevin after his dog.
Chang explains that he found the number in the vents but kept on chickening out of calling, provoking Jeff to kiss Alessandra in order to elicit a confession.
After seeing the opposition displayed by Jeff, Lorraine (Lisa Long) of the MacGuffin Neurological Institute grants the funds to the college.
While venting his frustrations, he used the slur "nigger"; episode director Jay Chandrasekhar argued that Chase's use of the word was "political," and an attempt to point out how racist his character had become.
