Lincoln overhears his parents having a conversation, and mistakenly believes that they're planning to get rid of him and his sisters.
One typical Saturday morning at the Loud House, in which Lincoln maneuvers and dodges his sisters' destructive antics on his way to the bathroom, he hears his parents having an argument through the air vent. His mother is demanding that her husband get rid of "all eleven" by tomorrow for garbage day. Lincoln believes that she's talking about him and his sisters, and runs out of the bathroom to tell them. What he doesn't know is that Mom is really telling Dad to get rid of his collection of novelty neckties, even though he loves ties.
The girls refuse to believe him, believing it to be paranoia, only to become convinced when Lincoln brings Lori into the bathroom, and has her listen to the argument out of context. Believing their wild and crazy natures are to blame, they decide to work together to give up their vices, and clean up the house. Afterward, they hear their parents again through the vent, and it appears that Mom has decides that she won't get rid of them all...instead, she will only let Dad keep one. As they decide which ones to get rid of, they single the kids out one by one until it apparently leaves Lincoln as the one they'll keep.
Lincoln is ecstatic that he'll finally get to be an only child, much to his sisters' offense and anger. As they leave to pack up their things, Lincoln hears Dad saying that he can't pick a favorite, because it's hard, and Mom begs him to get rid of one. Dad says he'll get rid of "the one with the white hair" (in reality, it's a "white hare" tie from Easter). Believing that he's getting kicked out, Lincoln sadly goes to pack up his belongings and prepares to run away from home, but he gives his sisters all of his most prized possessions.
Feeling sorry for their only brother, the girls decide to confront their parents about the issue. When they go into their parents' room, the kids finally find out that they were really talking about ties. They confess to their parents them about their assumptions, and they reassure their children that they wouldn't think of getting rid of them. As they leave the room, Lincoln sees Dad wearing the Easter tie and thinks that he should get rid of it. The next Saturday, Lincoln and his sisters resume their usual antics, having learned never to eavesdrop again. However, when Lincoln hears his father complaining about his wife having "a bun in the oven", he assumes the worst, and runs out to tell his sisters (not knowing that Dad meant it literally, as he can only eat gluten-free foods).
