"Sailor Mouth" is a SpongeBob SquarePants episode from season two. In this episode, SpongeBob learns a bad word on the dumpster behind the Krusty Krab.



The Krusty Krab has reached closing time and SpongeBob is about to leave, but is ordered by Mr. Krabs to take the trash on his way out. When SpongeBob goes around to the back of the restaurant, he peruses some of the dumpster writing, one passage in particular beginning: "Krabs is a..." As SpongeBob reads the last word, a nearby garbage man becomes disgusted and rebukes his use of the word. Confused, SpongeBob repeats this new word to the arriving Patrick, who believes it to be a "sentence enhancer" used in refined conversation. They quickly take to this new addition to their vocabulary.

Mr. Krabs wonders what happened to his customer.

The next day, SpongeBob walks into the Krusty Krab and greets Patrick with their new word before sharing it with everyone else over the intercom. Squidward and the Krusty Krab customers are appalled by what they hear and leave. While in the bathroom, Mr. Krabs is alerted to the empty restaurant and rushes out. He questions Squidward of what happened, Squidward explains the situation of the two learning and announcing their new word.


"Bad word?! Blegh, blegh!"

Mr. Krabs asks what SpongeBob and Patrick's new word was and Squidward explains it, as a disgusted Mr. Krabs sternly informs them that it is actually the eleventh of thirteen vulgar words that should never be uttered. SpongeBob and Patrick wipe the expletive from their tongues and promise Mr. Krabs that they will never use it again.

Later, at SpongeBob's house, the friends play a rousing game of Eels and Escalators. Patrick keeps moving up escalators while SpongeBob gets sent down the eels. After losing the game, SpongeBob angrily shouts out "Number 11". Patrick then races to the Krusty Krab to tattle to Mr. Krabs while SpongeBob tries to stop him. During the chase, Patrick repeats the swear word, giving SpongeBob the excuse to tell on him instead. Thanks to Patrick's detour aboard an ice cream truck, SpongeBob reaches the Krusty Krab first and rushes to Mr. Krabs. However, SpongeBob can't get to the point, giving Patrick time to catch up and add to the clamor. Eventually, Mr. Krabs commands them to spit out what they mean to say, which turns out to be the bad word.

Enraged, Mr. Krabs takes SpongeBob and Patrick outside and tells them to wait. Fearing their upcoming retribution, the two friends apologize to each other and vow to strike the word

"That's all 13"

permanently from their lips. Mr. Krabs returns with cans of paint for them to give the Krusty Krab a fresh coat as punishment. However, he hits his foot on a rock, and in his pain, he shouts all thirteen expletives. Once SpongeBob and Patrick tally the curses, they run to Mama Krabs' house to tell on her son. As Mama Krabs answers the door, she is greeted by a cacophony of swearing from all three of them, causing her to faint.

Mr. Krabs (while taking change from her) reprimands SpongeBob and Patrick for using such salty language in front of his mother. However Mama Krabs, quickly regains consciousness, scolds all three for their sailor mouths and sets them to work painting her house. After some time, she decides to reward them with some lemonade. On her way to get it, she hits her foot on a rock and shouts in pain. What they take to be a bad word, however, is actually the car horn of Old Man Jenkins' jalopy, with Old Man Jenkins saying "Howdy, Mrs. K!" giving them all a good laugh.

  • This episode is #16 on Tom Kenny's Top 20 on iTunes. His description says:

"This was also one of the silliest recording sessions ever. We had to come up with fake 'cuss words' to stick in the dialogue to be 'bleeped out' later. I was laughing so hard, they recorded me while I lay on the floor of the sound booth."

  • This episode became controversial, as it teaches children about inappropriate words, despite the episode censoring swearing with marine sound effects (i.e. foghorn, seal barking, dolphin chirping, etc.) so the kids don’t know what they said.
  • This episode also drew criticism from the Parents' Television Council, critics and some of the show's fans since they felt it encouraged children to use profanity. Despite this, the episode's intent was to deter swearing and show and that it results in being punished. When Mr. Krabs told Patrick and SpongeBob they were using bad words, they were horrified. When they all used them again, they were punished with painting the Krusty Krab and Mrs. Krabs' house.
  • "Sailor Mouth" was ranked #96 during the Best Day Ever event on November 9–10, 2006.
  • As of May 11, 2017, The Internet Movie Database (IMDB) gives this episode a rating of 9.3/10 based on 381 ratings by users.[1] users give this episode a rating of 9.1/10 based on 195 votes.[2]




  • SpongeBob had presumably sworn before in "Krusty Love," two episodes [dolphin chirp] prior to this. The swears in said episode were not bleeped, but either gibberish or profanities native only to ocean dwellers and they may not have been as awful as the ones said in "Sailor Mouth."
  • If one were to look closely on the dumpster, one can see the words "Patchy was here." This is a reference to Patchy the Pirate.
  • According to two interviews found here and here, the idea for this episode came from a childhood experience:
    • Learning a curse word is a classic thing that all kids go through. It was inspired by creative director Derek Drymon's experience of getting in trouble as a child for using the f-word in front of his mother. Drymon said, "The scene where Patrick is running to Mr. Krabs to tattle, with SpongeBob chasing him, is pretty much how it happened in real life." The end of the episode, where Mr. Krabs uses more profanity than SpongeBob and Patrick, was inspired "by the fact that my Drymon's mother has a sailor mouth herself."
  • In the SpongeBob SquarePants Movie video game, bad word number 11 is said twice in Planktopolis.
  • This episode was quoted to be Chris Pine's favorite episode.
  • In Croatian dub, the episode name is "Prostaci" translating to "Hecklers."
  • This episode is based on the reputation of sailors to use an abundance of profanities. The episode's title is based on the term "sailor mouth," meaning someone who swears a lot. Other terms include "swearing like a sailor." Among other names are foul-mouth and potty mouth (no relation to Potty the Parrot).
  • In the Russian dub, the amount of bad words Squidward knows is 8 instead of 7.
  • In the Brazilian dubbing, Betsy Krabs has a deep masculine voice.
  • Dolphin noises are heard in other episodes, but they are not used to censor expletives. An example would be the dolphin noises in "Jellyfish Jam." Another one would be SpongeBob making dolphin noises in "The Paper" and "You Don't Know Sponge."
  • Some of the dumpster writings:
    • Up with bubbles, down with air
    • Patchy was here
    • Dogfish ♥s Catfish
    • Starfish rool (reference to Patrick)
    • Nematodes are people, too
    • Squidward smells GOOD (the last word added by SpongeBob, who assumed that the writing was unfinished).
    • Krabs is a (dolphin chirp)
  • The "Squidward Smells" writing behind the green mess on the dumpster looks very similar to the "Something Smells" title card both in appearance and name.
  • Patrick calling Mr. Krabs a "red sweaty guy" may be a reference to the season one episode, "Arrgh!"
  • When Squidward whispered in Mr. Krabs about what word SpongeBob said, he actually said "Johnny Vandalism."
  • Word number 11 (dolphin chirp) was later said by a seagull during the Rap Battle in The SpongeBob Movie: Sponge Out of Water.
    • In the Broadway musical, after Plankton's cover is blown, Mr. Krabs calls Plankton a (dolphin chirp), to which Plankton replies, "How dare you call me a (dolphin chirp)!"
  • This episode and "Artist Unknown" are the first episodes to premiere after the 9/11/2001 attack which aired 10 days after the attack.
  • The dolphin chirp sounds is actually a sped-up kookaburra originally used in the 1963 film "Flipper", and is still available  from the first volume of The Premiere Edition from The Hollywood Edge sound effects library released in 1990.
  • The Number 11 is considered the "F-word" or the "S-word"

Errors & Goofs

  • When Mr. Krabs asks, "What kind of things?" the closed-caption says "What things?"
  • When the mama octopus is blocking her children's ears, the cap on the son she misses is red, but when the child is shown up close, his cap is blue.
  • When SpongeBob says: "Yea verily. Now, let's play a nice wholesome game of "Eels and Escalators." It shows the game board, but SpongeBob's left arm and the dice that SpongeBob had on his left hand are missing, while Patrick is sitting down. The next scene when Patrick says: "Oh boy, my favorite!" He is lying down, again. This may be due to the still paint scene error.
  • When Mr. Krabs says: "From top to bottom." Before his right foot hits the rock, he had his teeth together because his mouth wasn't in sync with the dialogue.
  • When Mr. Krabs was at the bathroom on the toilet his naked bottom was seen. And his right foot got hit, he held his left foot which was uninjured. Mama Krabs had the same error.
  • When Mr. Krabs pulls the penny out of Betsy Krabs' pocket, it is nickel instead of copper.
  • When SpongeBob and Patrick promise to Mr. Krabs that they'll never use number 11 again, one of SpongeBob's eyelashes is missing.
  • When Mama Krabs goes to SpongeBob, Patrick and Mr. Krabs and says: "I guess you three scallywags have earned a glass of lemonade.", dots on her claw became blue for a moment.
  • Just before Patrick says “Oooooh! You said number eleven!”, he bounces for a split second.
