Several of the squad members give Terry yogurt with a GPS device hidden inside, allowing them to track his movements when he leaves the precinct in search of the championship belt. The squad members are shown giving him the yogurt cups over the course of several days. The devices would have passed through his system and been excreted within hours of consumption. There's no way a GPS device hidden in his food would still be inside him days later.
Captain Holt wears his Commendation breast bar above his World Trade Center Breast Bar. When the WTC bar is worn, it is worn above all other medals, but below the American Flag bar.
Amy brags that Jake couldn't have stolen the key to her safe because the key has been in her shoe the whole time. She then reaches down to her waist and produces the key, not her shoe.
In a flashback, Amy is shown arriving for her first day at the 9-9, 8 years prior. 8 years prior would place her arrival at the precinct in late 2009, however, The Jimmy Jab Games (2014) showed her already working there in 2008.
When Scully notices Holt sweating, the scene focuses on the drop of sweat rolling down the side of Holt's face, then shows it to drop on the carpet a foot or two away from his chair, which is impossible (especially since Holt is sitting still...aside from his actions under his desk).
When everyone is at Gina's desk to claim items to work on, a boom mic can be seen briefly at the top of the screen as Jake grabs the Reach-and-Play and the camera pans up and out.
At the beginning, it is revealed that Holt ate Jake's breakfast eggs, despite having made pretty clear that eating eggs for breakfast in unacceptable in the episode "The Audit" when Amy suggested they meet so he can mentor her, at breakfast, and teach her over eggs, to which he replied "Eggs for breakfast? You're farther behind than I thought"
When Hitchcock and Scully are confronting Holt about why he's sweating, Holt lies and claims he's sweating due to an erotic video of a gymnast accidentally splitting his leotard. When Hitchcock doesn't believe him, he tells Holt to show them the erotica. Erotica is defined as "literary or artistic works having an erotic theme or quality." Since the alleged video was of something that happened unintentionally, it cannot be defined as erotica.
