"Earworm" is a SpongeBob SquarePants episode from season seven. In this episode, SpongeBob gets addicted to a song, and can't stop singing it.



SpongeBob is shown at the Krusty Krab during closing time with Mr. Krabs and Squidward. He is in the kitchen and starts singing a song. Squidward gets annoyed by SpongeBob's singing. Mr. Krabs comes and says to mop the floor. Squidward tells SpongeBob again to stop singing and then puts on the radio, but it's playing "Musical Doodle", so SpongeBob picks up the radio and starts dancing and singing to it. After it ends, SpongeBob sighs happily. Afterwards, Mr. Krabs says it's closing time again and Squidward runs out saying "Freedom!" SpongeBob is sitting down on a table, singing to the song and Mr. Krabs yells his name.

SpongeBob floats out of the Krusty Krab and lands outside a Record Shop. He hears "Musical Doodle" playing. He then buys the record and goes home, opens up Gary's shell, revealing a record player, and plays the song until bedtime.


SpongeBob says "Come to bed when you feel like it." He goes to sleep but then starts whistling the song. He goes back downstairs to listen to the song again.

He is then shown at the Krusty Krab the next day, looking very tired. Mr. Krabs warns him to get to work. Mr Krabs hears SpongeBob singing the "Musical Doodle." He is warned to stop singing that song again, but finds it very hard not to. He hands out Krabby Patties while singing the song, annoying the customers in the process. Mr. Krabs comes out of his office to see what's wrong. All the customers blame SpongeBob for annoying them. Mr. Krabs warns SpongeBob once again to stop singing the song or else he will send him home. In the kitchen, SpongeBob's eyelids form into mouths and start singing the song - the same thing happens with his back.

In the next scene, the kitchen is shown absolutely wrecked, with "doodle" written on the walls and everything else wrecked as well. Also, there are condiments and patty batter all over the wall. After Mr. Krabs tells SpongeBob to leave, the latter seems that he has completely lost it.

He goes home while singing the song - Sandy, Mr. Krabs, Patrick, and Squidward follow him, tie him to a chair, and gag him. Sandy explains that he has an "earworm" - an infection in which someone is stuck on a catchy song and is unable to stop singing; the more the person sings the song, the more infected and stronger the infection gets and more crazier the person gets.

"Don't do that Mr. Krabs!"

Mr. Krabs wants to just pull the earworm out but Sandy says that they can't do that or else it will damage SpongeBob's brain and it can only be cured if another song gets stuck in their head. Mr. Krabs sings a sea-shanty and Sandy sings a Western song, but none succeed. Sandy says

"someone with musical talent" can cure him (in this case, Squidward). Squidward starts playing his clarinet. The earworm gets annoyed and leaves. Squidward is then shown in bed, praising himself. The earworm comes and goes into Squidward, and now the latter has the earworm and is humming his song. Squidward then screams loudly as the episode ends for unknown reasons, inferring he probably found out he caught the earworm.

  • This episode was originally going to premiere with "Buried in Time," as said from a brief crew meeting in August 2010, but was paired up with "The Abrasive Side" instead.[citation needed]
  • The song SpongeBob bought was on a record instead of a CD or a digital download like it would be in modern times.
  • The title card background is identical to that of "Bubblestand," except the letters are written in pink and there are no bubbles.
  • This is the second appearance of Gary's record player. The first was "Your Shoe's Untied."
  • The Gary clock from "Procrastination" appears again.
  • The song lyrics match what happens in the episode. For example, "The song you escaped from is back again! You wonder if the madness will ever end! Trying to escape is futile! So just listen now to the Musical Doodle! Listen again to the Musical Doodle!"
  • Sandy said they couldn't rip the earworm out or it would damage SpongeBob's brain. However, she stuck her hand all the way into SpongeBob's head and put a hat on the earworm, nearly touching the brain.
  • To prevent anyone else from getting infected by the earworm, they could have just squished it before it infected Squidward.
  • Sandy mentions the episode title when she says "You're suffering from a condition known as Earworm. You see, when your brain becomes stuck on a catchy tune, you're spectacle with Earworm infection and you've got a nasty one there."
  • This episode premiered in the UK four years after "Wigstruck" premiered.
  • This episode premiered 10 years after the premiere of "Mermaid Man and Barnacle Boy III" and "Squirrel Jokes" and one year after the premiere of "Greasy Buffoons" and "Model Sponge."
  • The Earworm enters Squidward's brain at the end of the episode, this could presumably be its revenge for Squidward causing it to leave SpongeBob's brain.


  • Usually SpongeBob's brain is pink, but in this episode, it is blue.
  • Typically, one's eardrum prevents them reaching to their brain through their ear alone. Though, it is possible that sponges don't have eardrums (hinted in "Blackened Sponge," even though SpongeBob has an eardrum in "The Inside Job").
