"The Loud House" (also known as "Bathroom Break!!") is the pilot short for the series.
Lincoln tries to get to the bathroom, but he has to go through many obstacles along the way.
The story opens up with a picture of a boy, and his ten sisters. The boy tells us not to let the picture fool us, as growing up in a big family isn't that perfect. With proof, he shows us the chaos just outside his room. "This is...THE LOUD HOUSE." The boy is Lincoln Loud, and he explains that surviving in a big family is a real challenge. One obstacle he endures is trying to get a turn in the bathroom. He informs us of his Three P's to Go Poo and Pee. The Three P's are Patience, Perseverance, and finally, Problem Solving. They are sure to get him into the bathroom, especially if he goes in the last second. And with no time left, Lincoln feels the strain and gets ready to go.
He asks his big sister Luna, a rocker girl, to play a little tune for him on his travels and she obliges. His younger sister Lucy, a gloomy gothic girl, wants to read him a poem, but Lincoln tells her to wait until he's done with his business. His older sister Luan, a comedian, tries to squirt him with her trick flower, but Lincoln ducks in time, knowing that trick all too well, but Luan squirts water from a flower on her shoes into his mouth. Suddenly, his older sister Lynn, a sports jock, comes careening down the hall on her motorbike, while playing sports in the house. He gets out of the way in time, just before she crashed into something. Just then, his little sister Lola, a pageant queen, wants him to play "Fashion Photographer" with her. If he doesn't, she'll tell their mother that he was reading comics on the roof in his underwear again. Not wanting their mom to know and wondering how she knows that, he accepts and takes some photos while Lola strikes poses. Just then, Lola's twin sister Lana, who is a bit more of a tomboy, and a handyman, comes by to show Lincoln her mud pie. But Lincoln's strain starts getting to him and he bolts for the bathroom. Lucy checks to see if he's ready, but he says he's not. He leaps over his little sister Lisa, a 4-year-old genius, and reminds her to carry the 1 in her mathematical formula she's writing on the wall. Lincoln's older sister Leni, a stereotypical dumb blonde, is trying to figure out how to turn on the vacuum and manages to do so while sucking up Lincoln's shirt and pants in the process. Lincoln is almost at the bathroom, but his older sister Lori, the first born, beats him to it. Lincoln tells her it's not fair, and that she cut in front of him, but Lori believes she gets first born privilege and shuts herself in. As Lincoln is forced to wait, Lucy comes by and thinks he's done with his business, and reads her poem to him, only to make Lincoln go even more. Just then, Lincoln's younger sister Lily, a baby, walks by with her dirty diaper, and he gets an idea on using the third P: Problem Solving, to get Lori out of the bathroom.
As Lori takes care of her business, Lincoln comes in and closes the door, containing something that disturbs Lori so much, that she gets terrified and runs out of the bathroom in fear. His other sisters look on in confusion, and Lincoln reveals to have gotten Lily's dirty diaper off her, and used it to shoo Lori out of the bathroom, to which they all cheer for his bravery. Lincoln throws the diaper away and says that surviving in a big family is a challenge, but not impossible, and finally, goes to take care of his business on the toilet. However, he finds out that there's no toilet paper left. He asks his sisters for a new roll, but they can't hear him over the loud commotion and chaos they're causing.
Lisa has no lines in this short, but was heard cheering for Lincoln with her sisters.
