Pimemento

In the cold open, Jake finds Hitchcock asleep in the break room once again and tries pranking him by tying his shoelaces together. When they check in on him afterwards, they find him somehow choking on his shoelaces tied around his neck.

Jake (Andy Samberg) has reluctantly promised Amy (Melissa Fumero) that he won't tell Boyle (Joe Lo Truglio) that they are trying to get pregnant because of Boyle's tendency to overreact to everything Jake does, and Jake tries to avoid spending time with Boyle so he won't be tempted to tell him. Meanwhile, Adrian Pimento (Jason Mantzoukas) asks Jake and Boyle for help when he thinks he is being targeted by assassins. However, while Pimento is describing his history of events, they deduce that Pimento is suffering what Jake calls Memento disease and everyone else calls Finding Dory disease (anterograde amnesia), failing to remember anything from the past four months except that his most recent client hired him to find evidence of her husband's adultery.

They interview Pimento's doctor, Dr. Jones (Jim Rash), who explains that the numerous head injuries Pimento received during all of his dangerous missions are the cause of his condition and he has prescribed medication. Later, Pimento is shot in the shoulder by an unknown suspect and is taken to the hospital. While visiting him, Jake, desperate to confide in another person about his plans to start a family, tells Pimento, under the assumption that he will forget it immediately, the same way he has forgotten all of his other new memories. But Pimento refers to how Jake will be a good father in front of Boyle, which hurts Boyle's feelings that Jake didn't tell him first.

Jake deduces that Dr. Jones is the husband of Pimento's client trying to cover up Pimento's discovery of his cheating. Jones tries to restrain Pimento in one of the upper rooms of his skyscraper building, but he escapes onto the ledge. Jake and Boyle repair their friendship and help Pimento get back into the office safely. Pimento's full memory finally returns.

Meanwhile, the rest of the precinct is suffering through the annual Human Resources seminar on workplace conflict. Amy obtains a copy of the manual and suggests everyone study it in advance; this results in getting through the seminar in only four hours. But this backfires when told that the seminar must last the allotted six hours and so they will participate in extra activities to use up the remaining time. The extra activity involves the squad talking about their insecurities and soon, everyone turns against each other by mentioning all their flaws. However, they realize that revealing their flaws actually made them better people by trying to make up for everything.
