Plot
During school one day, Nate, Francis and Teddy learn that the school is having a yearbook meeting. Remembering how badly the last year's yearbook turned out, the three decide to attend the meeting to make the new yearbook more "memorable". Upon arriving, however, Nate discovers to his shock that Gina has been made the editor for the yearbook. Fearing that Gina will make the yearbook all about herself, Nate decides to nominate Francis to be the yearbook's co-editor, and Gina is forced to comply when Mrs. Hickson approves of the request.
Wanting to take candids for the yearbook, Nate asks Francis to obtain one of the school's cameras from Mrs. Godfrey. Francis agrees to do so, but expresses concerns over Nate's messy tendencies, and makes him promise to keep the camera safe. An encounter with school bully Randy Betancourt in the school yard almost ends in disaster, after Randy snatches the camera from Nate and throws it into the air, but Nick Blonsky (a dimwitted, troublesome student who was responsible for everything that went wrong with the previous year's yearbook) manages to catch the camera before it hits the ground, and hands it back to Nate, though not after he accuses Nate of being irresponsible with the camera.
The next day, Nate overhears Dee Dee asking Gina to jump rope with her, and gets the idea to use the opportunity to get an embarrassing photo of her. After opening his overstuffed locker, however, Nate is unable to locate the camera. Francis gets mad at Nate, accusing him of losing the camera, and blaming it on him being a slob. In the ensuing argument, Nate accidentally reveals that Francis's middle name is "Butthurst" (which Nate had promised in third grade to keep a secret). Immediately regretting his action, Nate tries to apologise, only for Francis to storm off.
The next morning, Nate postulates the idea that Randy stole the camera from his locker, and tells Dee Dee his theory. Whilst preparing for first period, Nate, Dee Dee and Teddy overhear Francis talking to Mrs. Godfrey, during which he takes responsibility for losing the camera. Nate, Teddy and Dee Dee then get the idea to have Teddy's uncle Pedro hypnotise Nate into becoming neat and organised, believing that it will help them find the camera and reinstate Nate's friendship with Francis. The hypnotism works, and Nate ends up cleaning both his bedroom and his locker, but he still doesn't find the camera, and the hypnotism also starts to prevent him from enjoying his own hobbies and interests.
Nate's change in personality causes Principal Nichols to make him a hall monitor. During his shift, Nate notices Nick Blonsky, who appears to be holding the camera, but Nick ends up escaping before he can confront him. During lunch in the cafetorium, Nate sees Randy bullying Francis about his middle name, causing him to lose his temper and attack Randy. Mrs. Czerwicki intervenes and sends Nate to the principal's office. After a lecture from Principal Nichols, Nate encounters Francis, who asks him about Pedro's hypnotism. During the conversation, Nate shows Francis his clean locker, only to discover the camera is inside. Nick then appears and confesses that he stole the camera, just because he wanted to see how Nate and Francis would react. Suddenly, Dee Dee appears and reveals that she secretly recorded the confession on her phone, and Nick flees in embarrassment. At Dee Dee's encouragement, Nate and Francis reconcile their friendship, and Nate realizes that the fight with Randy has made him a slob again after Dee Dee points out the dirtiness of his shirt.
The incident with the camera causes Nick to be suspended for a week. A few days later, the school holds their annual Trivia Slam, giving Nate the opportunity to take the candids. Thanks to Nate's phobia of cats, Nate answers the winning question correctly, and Nate's team beats Gina's team. Francis ultimately ends up deciding that he likes Nate better as a slob.
