At Mrs. Puff's Boating School, it is time to select the hall monitor for the day. Mrs. Puff notices that SpongeBob is the only one who has yet to serve as hall monitor. SpongeBob then moves forward, and after desperately attempting to find another candidate, she is forced to give the hall monitor duties to SpongeBob.
After being elected as Boating School Hall Monitor, SpongeBob gives a very long speech, which ends up lasting the entire school day, and also his entire time as the hall monitor. Out of sympathy, Mrs. Puff allows SpongeBob to at least wear his uniform until the next day.
However, SpongeBob goes above and beyond the call of duty, and decides to become the hall monitor of the city, with disastrous results. His activities include giving directions to traffic, resulting in a massive pile-up, and attacking a couple in the guise of the "Open Window Maniac," with the intention of showing them the dangers of leaving a house window open. Later, SpongeBob finds Patrick eating a strawberry ice cream, which drips onto the ground, and labels him as a criminal. Then, a newspaper boy comes up to SpongeBob and Patrick gives them newspaper titled "Maniac strikes Bikini Bottom." SpongeBob looks at the newspaper headline alerting about a maniac causing trouble around town without realizing it's himself. SpongeBob suggests they stop this maniac and turns Patrick over a new leaf as a deputy.
They end up getting ice cream twice (Patrick's idea of a scandal), and then decide to split up to find the maniac, communicating using walkie-talkies. Two policemen ask Patrick if he's seen the maniac, and show him a picture of SpongeBob, which he at first mistakes for the actual maniac, but fails to recognize as SpongeBob. Soon, night suddenly falls and Patrick gets frightened. He sees SpongeBob in the distance across the street, who he recognizes as the maniac but not as SpongeBob.
He alerts SpongeBob to this through his walkie-talkie, and SpongeBob attempts to escape the maniac. Everywhere he goes, Patrick tells him the maniac is there, making SpongeBob believe that the maniac is following him. Eventually, SpongeBob sees a wanted poster for himself and realizes that he is the maniac.
The police arrive to arrest him, and Mrs. Puff appears to explain the situation to them, saying that he is her responsibility. The police interpret this as taking responsibility for the crimes, and she is arrested. She is working with the whole class on their essay while she is being taped on TV until she tells SpongeBob that he needs to see her after class, 6 months from now.
This episode aired on Sean Charmatz's 19th birthday.
This is the second time SpongeBob gets a deep voice.
SpongeBob's speech includes the line "Friends, students, juvenile delinquents...," a parody of Mark Antony's "Friends, romans, countrymen..." from Shakespeare's Julius Caesar. The music that plays in the background during the speech is Elgar's Pomp and Circumstance which is played at graduation ceremonies.
Harold was not listed as a student, This mistake happens again in "Oral Report."
When the police arrives and ask Patrick about the maniac, Officer John's eyelids are the same color as Officer Rob's. However, when they talk to Patrick, Officer John's eyelids are orange.
SpongeBob tells Patrick that the crime he committed was throwing his ice cream on the ground, but as SpongeBob and Patrick leave the ice cream shop for the second time, SpongeBob says, "This isn't working. We've got to do something else" and throws his ice cream cone behind him.
When SpongeBob is surrounded by the policemen, all of the policemen are only seen in four colors.
After SpongeBob crashes through the fence while in the mailbox, he lies on the ground as a wanted sign floats down and lands on his face. It is evident that the paper is upside down from his point of view until he looks at it, turns it around, and holds it up. Then, it is upright.
When SpongeBob first starts directing traffic, he turns left, and you can see the whistle in his mouth is upside-down. When he turns right, the whistle is right-side up. When SpongeBob turns left a few more times, the whistle switches between upside-down or right-side up.
When Mrs. Puff tries to avoid naming SpongeBob as hall monitor, she names Henry, Vera, and Clayton, whose names weren't on the list. She also omits the names of some students whose names were on the list (including Bart).
If Beth graduated, her name shouldn't still be on the list of hall monitors.
When SpongeBob says "I must act!," the road disappears.
When there's the closeup on the ice-cream, it's on the other side. It goes back by SpongeBob and Patrick in the next shot. The road also disappears again in the shot and for the rest of the episode in that area.
When SpongeBob tells Patrick to come down from the wall, Patrick was standing once he got off the wall; but when the camera is zoomed out, Patrick is seen sitting on SpongeBob.
