Potty Mouth

"Potty Mouth" is the twenty-second episode of the second season and the seventy-fourth episode of The Loud House.

​Plot
When the kids hear Lily apparently curse, they believe that they have been a bad influence on her, and decide to change their behavior for the future.

Synopsis
As the kids are enjoying themselves in the living room, Rita and Lynn Sr. are heading off to the mall, because Dr. Shuttleworth of the Daycare Academy, is coming to interview Lily, and Lynn Sr. needs a more appropriate tie. Once they head out, Lynn changes the TV channel, because Dessert Storm is on right now, and Lily suddenly exclaims "dannit." This causes her siblings to gasp in horror, because they think that Lily has just said the "D" word. The siblings fear that Lily learned the word from them, because in past experiences, the kids have gotten into some predicaments that led them to crying out the "D" word in anger, and Lily was there to witness them saying it. Because of this, the siblings are worried about potentially being a bad influence on Lily, and fear that if Lily says the "D" word in front of Dr. Shuttleworth during the interview, she won't get accepted into the daycare academy she runs. After refusing Lisa's idea of removing Lily's vocal cords, Lincoln comes up with a much better and safer idea: if Lily imitates their bad behavior, they should come up with better (and nicer) behaviors for her to imitate, and that way she won't say the "D" word in front of Dr. Shuttleworth (and possibly their parents).

The plan is set into action. Each of the siblings are tasked on reenacting the action that led them into saying the word. Throughout all of these, their faces would turn red, and are on the verge of saying the word, but they would say something else in hopes that Lily would mimic them. After nearly an hour of doing these actions, the siblings believe that Lily has forgotten all about the word. At that moment, Rita and Lynn Sr. arrive back, and begin prepping things up for Dr. Shuttleworth's arrival. One of the things they do is set a tray of snacks on the table. Lily tries to get one, but Lori tells her the snacks are not for Lily, causing her to exclaim "dannit" again, making the siblings realize that the plan didn't work.

Dr. Shuttleworth arrives, and is ready to interview Lily. Dr. Shuttleworth gives Lily several things to play with, such as a hardware set, a guitar, and a ball, but the siblings fear that Lily would do something that could lead to her yelling out the word, prompting them to confiscate the toys. When the kids become too bothersome with their meddling behavior, the parents tell the kids to leave, but Dr. Shuttleworth tells them that they should leave too, as she just wants to be with Lily. The siblings huddle up, and says that they need a plan to get Lily out of the room. Lincoln suggests on making Lisa take Lily's place, because of the fact that she wears a wig after a nuclear experiment gone wrong, and wearing dentures. Luan takes Lily away under the guise that she soiled her diaper, and put Lisa, disguised as Lily, in Lily's place. However, Lisa begins displaying some of her smart aleck attitude, like painting complex formulaic equations, doing an impressive xylophone solo, and able to tell Dr. Shuttleworth what type of condition her eyes are in, just by looking at her glasses. This prompts Luna to tell Lisa that she needs to act more like a 1 year old, which she does by intentionally soiling her diaper.

Later, Dr. Shuttleworth is done interviewing Lily, and concludes that due to the things Lisa did, she's allowed into the academy. Just before Dr. Shuttleworth leaves, she takes the snacks on the table with her, causing Lily to exclaim "dannit." Everybody is left horrified at this action, and the remaining siblings come to her defense by pleadingly explaining to Dr. Shuttleworth that Lily didn't mean to say that word, and say that they've been a bad influence on her. Dr. Shuttleworth, however, laughs at this, explaining to them that Lily wasn't saying the "D" word--according to Dr. Shuttleworth, Lily was apparently just trying to say "donut," and with some help, Lily pronounces the word correctly after being given a donut by the doctor.

After Dr. Shuttleworth leaves, Lynn Sr. and Rita start cheering about Lily getting into the daycare academy, while the kids are glad at the fact that they apparently weren't a bad influence on their youngest sibling. However, as they cheer, Charles comes by, and snatches Lily's donut, causing Lily to cry out an actual (more offensive) curse word in fury (which is bleeped out), causing the family to look on, and gasp in sheer horror.

Trivia

 * This is the tenth episode where Lincoln isn't the main focus (instead, Lily is).
 * This is the first time Lily is the main focus in Season 2.
 * As of this episode, all five of Lincoln's younger sisters have an episode centered around each them.
 * Episode 12 of Season 2 is the first episode where neither segment focuses on Lincoln.
 * This is the second episode that involves swearing, and there was a brief joke about it in "Get the Message".
 * This is the first time a baby swears on the show.
 * The episode has a lot of English language references that could be difficult to be dubbed to other languages.
 * This is the first episode of Season 2 written by Michael Rubiner, whose last writing credit was Season 1's "Study Muffin", which premiered back in October 2016, eight months before this episode's premiere.
 * This is the third episode where one sibling impersonates another. The first episode was "Cover Girls", and the second was "The Loudest Yard".
 * This episode likely takes place after "Making the Grade", because Lisa could see well without glasses.
 * This is one of the few times that Lincoln doesn't use a very long title for an operation.
 * The song Lisa raps to get Lily to mimic her from saying the "D" word is the Blarney the Dinosaur theme, first heard in "For Bros About to Rock".
 * Apparently, due to some experiments-gone-wrong (one of which being a nuclear experiment), Lisa:
 * Is bald, and has to wear a wig.
 * Has an extra toe on one of her feet.
 * Has to wear false teeth.
 * It's unknown if Lisa's going to cure herself.
 * The closed captioning for the episode shows that Lily said "dannit.", before her actual saying is revealed.
 * If one looks at the siblings' lips, they weren't saying "dannit". They were saying the actual "D" word.
 * The Loud kids play Nose Goes to decide who changes Lisa's diaper, which they did in "Suite and Sour", and Lincoln lost again.
 * This is the second time Lily says "kitty cat". The first time was in "Suite and Sour".
 * This is the second time Lily sneezes. The first was "One Flu Over the Loud House", and the third was "Room with a Feud".
 * This is the second time Lily has played the drums with Luna, with the first time being in "Changing the Baby".
 * This is the second episode to show Lincoln using his yo-yo, with the first being in "Butterfly Effect".
 * Incidents that caused Lily's siblings to openly yell out the "D" word in front of her, as well as the sound that blocked off their shouting of the word:
 * Lincoln - Accidentally broke the TV; the TV breaking.
 * Lori & Leni - Ripped a sweater that they were fighting over; the washing machine buzzing.
 * Luna - Broke one of her guitar strings; a loud guitar riff.
 * Lynn - Her baseball landed in the neighbor's yard and, presumably, got destroyed by a lawnmower; the lawnmower whirring.
 * Lana - Banged her hammer against her thumb; Lola honking the horn on her Princess Car.
 * Lola - Crashed her Princess Car; the airbag deploying.
 * Lisa - Sang a rap song that had the word; a squeaky toy.
 * Luan and Lucy were the only siblings not shown to have said the "D" word (possibly off-screen).
 * It is unknown if the Loud siblings (minus Lily) were grounded for teaching Lily a curse word (even if it was unintentional).
 * It is most likely they did get punished, but were punished offscreen (since people can't get in trouble if they curse on accident, but can get in trouble if they say it on purpose, and probably for the plan).
 * Or they probably did not because Rita and Lynn Sr. probably know it was an accident (but they might of gotten punished for teaching Lily the F-bomb).
 * This is currently the only episode so far to have an actual censored beep sound.
 * This is the first time Lisa has her chest uncovered onscreen.
 * This is the 5th episode where Lisa is seen without her glasses, the first four are "Picture Perfect", "Cover Girls", "Raw Deal", and "Making the Grade".
 * This is the fifteenth time Lincoln did not speak to the audience.
 * This episode reunited Mindy Sterling and Liliana Mumy, who previously worked on the Cartoon Network series  as Endive and Panini, respectively.
 * There are clues that indicate that Lily was actually saying "donut":
 * When Lynn changes the channel to Operation: Dessert Storm, the cover title has donuts on it.
 * Lily attempted to get a donut from the snack plate, but Lori took her away, and said that it was meant for Dr. Shuttleworth.
 * Lily was reaching out for Dr. Shuttleworth's purse, which had a donut.
 * It's possible that at the end of the episode, Lily may have said what's referred to as the "F-bomb" (or possibly the actual "D" word, or possibly the other one).
 * However, based on the way she moved her mouth, it is unlikely for her to have said the "D" word, since it would require her to open her mouth twice, when clearly she did only once.
 * In the Hebrew title card for the episode, the red "?#@*%!" in Lily's mouth is not present.
 * In the Swedish dub, Lily moaned while the beep was heard.
 * Lincoln's operation name: Operation Delete the "D" Word.
 * Irony: It turns out Lily was just trying to say donut.
 * Karma: The Loud siblings were interrupting Dr. Shuttleworth's interview with Lily, so they were all kicked out of the room.
 * Moral:
 * Watch your language in front of a younger person or other people.
 * Sometimes, swearing can offend others.
 * Don't jump to conclusions until you figure it out.
 * In this episode, Lisa wears a surgeon's outfit similar to the one in this episode's sister episode "L is for Love", albeit with a few differences.

Errors

 * Mindy Sterling, Dr. Shuttleworth's voice actress, isn't listed in the credits.
 * However, she was credited in the Brazilian dub.
 * While Lily is saying "Da da da", like Lynn during the plan of making Lily forgetting the "D" word, her eyelashes were missing.
 * While Luna is drumming with Lily, her eyelashes are missing.
 * During the beginning of the interview, Lily has eyebrows, which she normally doesn't have.
 * This is the third time that this error has happened. The other two instances were "Changing the Baby", and "Baby Steps".
 * There are five instances of disconnected eyelashes:
 * Rita's are disconnected when she tells the kids that she and Lynn Sr. are heading off to the mall.
 * Lynn's are disconnected when Lincoln reveals to his sisters that Lisa wears a wig.
 * They are also disconnected after Lisa reveals that she wears dentures.
 * Dr. Shuttleworth's are disconnected when she tells Rita and Lynn Sr. that Lily is accepted into the daycare academy.
 * Lily's are disconnected when she gets furious after Charles steals her donut.
 * Luan said "swap Lisa for Lily", when she meant "swap Lily for Lisa".
 * This affected to other foreign dubs.
 * But this was fixed in the Swedish dub.
 * When Lana is hiding in the bush with the rest of her siblings while observing Lisa, she has only two eyelashes on every eye instead of three.
 * Plot hole: Dr. Shuttleworth didn't notice significant differences between Lisa and Lily like lack of hair and additional toe.
 * In the Swedish dub, Luan calls Lily a him when she says "Where the heck would she have learned that?".
 * In the Chinese dub, the Chinese word "ke wu" was the curse word, although it meant "dang it" instead of the actual "D' word.
 * In the Latin American dub, when Lincoln loses the Dibs game, he shouts "Dem***os" (the D word in this dub), when in the original version he says "Dang it!".
 * When Lincoln gives thumbs up to Luna, he is lacking his chipped tooth.

Running Gags
