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 an extremely long speech, which ends up lasting the entire school day, and his entire time as the hall monitor (which puts the entire class to sleep). 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 scaring a couple out of their house in the guise of the "Open Window Maniac," with the intention of showing them the "dangers" of leaving a house window open. Later, SpongeBob comes across Patrick eating a strawberry ice cream cone and labels him a criminal after Patrick drops the ice cream on the ground.
Then, a newspaper boy comes up to SpongeBob and Patrick, and gives them a newspaper with the headline "Maniac strikes Bikini Bottom." SpongeBob looks at the newspaper headline alerting about a maniac causing trouble around town without realizing that he is the maniac. SpongeBob suggests they stop this maniac, which gives a saddened Patrick the chance to turn over a new leaf as a deputy. They end up getting ice cream twice as part of Patrick's ex-criminal advice and then decide to split up to find the maniac, communicating using walkie-talkies, and SpongeBob runs off.
Seconds after SpongeBob leaves, two police officers pull up next to Patrick. They ask him if he has seen the maniac, showing him a wanted poster with a picture of SpongeBob, which he at first mistakes for the actual maniac and screams with terror at the mere sight of the poster.
The cops patiently assure him that it is just a drawing and not the real thing, and instruct him to tell them if he has seen the person when they show the picture. Patrick agrees to cooperate, but he keeps screaming whenever the police show him the sketch. Eventually, the cops begin scaring him with the wanted poster on purpose by repeatedly showing and hiding the picture as Patrick screams every single time. The amused officers then drive off, suggesting to Patrick that he take the ice cream cone off his head.
Soon, night suddenly falls and Patrick gets frightened. He calls SpongeBob and asks him to return. SpongeBob comes back as Patrick finds a poster of the maniac before he sees SpongeBob in the distance across the street. However, Patrick, once again, recognizes him as the maniac rather than SpongeBob. He alerts SpongeBob through his walkie-talkie, and SpongeBob attempts to escape the maniac. Everywhere he goes, Patrick tells him the maniac is there, causing SpongeBob to hide in a mailbox for safety. Upon being told that the maniac is also in there, he bursts his arms and legs out of the mailbox, sprinting around the city in a blind panic. In his terrified state, he crashes through and topples several buildings and eventually crashes through a fence covered in the wanted posters. After seeing a poster from the fence, he finally realizes that... he is the maniac.
The police arrive to arrest SpongeBob, since he confessed, but Mrs. Puff appears and scolds SpongeBob for his foolish actions and destruction of the city, much to his sadness. She then explains the situation to them, saying that he is her responsibility. The police interpret this as taking responsibility for the crimes, and she is arrested instead.
Sometime later at Boating School, Mrs. Puff is working with the class on their essay while she is being taped on TV from jail, until she tells a remorseful SpongeBob that he needs to see her after class... six months from now.

- When Patrick spots the maniac (SpongeBob) in the dusk of night, he states the maniac is standing at the intersection of Conch Street and Coral Avenue. There is even a sign to indicate the intersection. But from where Patrick is standing, the intersection looks like just one straight road.
- 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.
