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's 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 equably better ear for music and soon buys one himself. Squidward then plays it around the town: first, he scares Dennis out of his wits as Dennis thinks he's being annoyed by ghosts and Squidward impersonates a baby and scares Sally 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 doesn't want to stop but then SpongeBob and Patrick (driving a boat) ask if he is sure he doesn't want to stop. Then Squidward sees that SpongeBob was trying to warn him that a cliff was ahead but there's 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 don't have the technology to remove it, they just left it there. SpongeBob and Patrick then play around the hospital with the whistles.

This episode is number 6 on Tom Kenny's Top 20 on iTunes. His description says:
"SpongeBob and Patrick drive Squidward nuts with their new slide whistles. I'm a sucker for any episode where a tiny thing gets on Squidward's nerves until he snaps. (Roger [sic] Bumpass is great at vocalizing Squidward’s 'losing it.')"
Squidward breaks the fourth wall by hiding himself with his robe from viewers, even though he is at home. Perhaps he knows he is on camera.
This is the second time Patrick is seen driving. The first was in "Driven to Tears."
After the woman fish yells "baby assaulter!," there is yelling and someone yells "assault your own baby!"
The title card is the same as when Patrick is chasing SpongeBob in an episode from an earlier season; "Big Pink Loser" also, it's similar to SpongeBob's wallpaper in the original episode "Help Wanted."
Ιn Greek version, this episode is called Η σφυρίχτρα which means The Slide Whistle.
In Polish version, this episode called Żart z gwizdkiem which means A Joke with Whistle.
The title is a pun to The Three Stooges.
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.
The sound of the slide whistles follow the background music at some points.
When Squidward falls off the cliff, in an explosion, SpongeBob and Patrick play the funeral march on their slide-whistles.
When SpongeBob and Patrick are explaining slide whistles to Squidward near the episode's beginning, Patrick looks (very slightly) off.
When Squidward finds SpongeBob and Patrick under the mat, SpongeBob’s socks are gone.
Sally is orange in this episode but is yellow in later scenes.
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.
The driver of the truck spits his coffee near an air vent. Later, the coffee and the vent are gone when Squidward drives it.
The gas in the gasoline truck should have caught on fire due to exposure to heat when the truck went through the burning hoop.
When Squidward drives through the Krusty Krab, the kitchen, bathrooms, freezer, and Mr. Krabs's office cannot be seen.
Purple Doctorfish says that they don't have the "technology" to remove the slide whistle from Squidward's throat while the whistle is only hanging from his throat by the tip.
A fish said that Squidward lives on "Conch Drive" when he actually lives on "Conch Street."
Mr. Krabs was never credited even though he actually had lines.
When Squidward was using his slide whistle around town, the people were annoyed by his antics, even forming an angry mob. However, when SpongeBob and Patrick use their slide whistles in the hospital, everyone thinks it's funny.
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."
