SpongeBob and Patrick get new slide whistles and keep playing them, much to the annoyance of Squidward. He becomes increasingly annoyed as they use the slide whistles as sound effects for everything he does. He eventually has enough of it and flees his house. SpongeBob and Patrick follow him, thinking he is finally playing with them and ignoring his cries to leave him alone. He snaps and grabs SpongeBob's slide whistle and uses it on them. SpongeBob says he has an equally better ear for music and soon buys one himself. Squidward then plays it around town: first, he scares Dennis out of his wits as Dennis thinks he iks being annoyed by ghosts and Squidward impersonates a baby and scares Sadie out of her wits, making her see Squidward as a "baby assaulter," resulting in the annoyance of a lot of people.
Soon, they form an angry mob and end on the warpath against Squidward. Squidward manages to take control over a gasoline tanker truck, destroys the Chum Bucket and the Krusty Krab, jumps over a row of boats through a ring of fire, and drives away from the mob. Squidward says he does not want to stop but then SpongeBob and Patrick (driving a boat) ask if he is sure he does not want to stop. Then Squidward sees that SpongeBob was trying to warn him that a cliff was ahead but there is nothing Squidward can do about it now. SpongeBob and Patrick stop just in time but the gasoline tanker truck keeps going and falls off the cliff, causing it to explode, much to the joy of the town as they see that Squidward is finally stopped. At the hospital, the whistle gets stuck in his throat and since they do not have the technology to remove it, they just left it there. SpongeBob and Patrick then play around the hospital with the whistles.

When the police officer is attacked by the worms, he says "I'm supposed to retire this week!" This is a reference to the captain of the Titanic, Edward J. Smith, when he died on the voyage before he was supposed to retire.
The scene with Squidward in the truck falling off the hill and people cheering is a reference to the 1971 movie, Duel where the truck driver falls off the hill and the protagonist starts cheering.

At the beginning of the episode when Squidward is bathing, the water is black then turns blue.
When SpongeBob and Patrick jump into the paintings, when they fly out, one of the paintings of Squidward's eyes change colors.

When Squidward gets in the driver's seat of the truck and takes the wheel, the wheel goes the opposite way he is turning it.
The worms should not have been called the "K-9" unit because "K-9" refers to the species name for dogs, "Canine." However Worms are Parodies of dogs so this makes sense.
When SpongeBob and Patrick drive to the cliff, after the explosion, the scene changes and the boat is gone.
When Squidward is first driving the truck, his feet are on the wheel, but his hands are on the slide whistle, so the truck shouldn't be moving.
