The episode begins with a scene at Springfield Elementary School, where Principal Skinner announces a new program aimed at improving the students' social skills. He introduces a new student, a boy named "Laddy," who is a rough and tough kid from a different school. Laddy's tough demeanor and lack of social graces immediately set him apart from the other students, and he quickly becomes a source of fascination and concern for the faculty and students alike.

As Laddy interacts with the other children, he displays a brash attitude and a penchant for trouble, which leads to a series of incidents that disrupt the school environment. Bart Simpson, intrigued by Laddy's rebellious nature, befriends him, and they begin to bond over their shared love for mischief. However, Laddy's behavior soon escalates, leading to a confrontation with Principal Skinner, who decides that Laddy needs to be refined and civilized.

In an effort to transform Laddy into a more socially acceptable student, Principal Skinner enlists the help of Marge Simpson, who is known for her nurturing nature. Marge agrees to take Laddy under her wing, believing that she can help him learn proper manners and etiquette. She begins by introducing him to various activities, such as cooking and attending social events, hoping to instill a sense of decorum in him.

As Marge works with Laddy, she faces numerous challenges. Laddy resists her attempts to change him, often rebelling against the lessons she tries to teach. Despite this, Marge remains patient and persistent, believing that there is a good kid beneath Laddy's tough exterior. Their relationship develops, and Laddy starts to show signs of improvement, albeit reluctantly.

Meanwhile, Bart becomes increasingly jealous of the attention Laddy receives from Marge. He feels overshadowed by Laddy's transformation and begins to act out, trying to sabotage Laddy's progress. Bart's antics lead to a series of comedic situations, including attempts to embarrass Laddy in front of their classmates. However, Laddy's newfound skills begin to earn him respect from the other students, which only fuels Bart's frustration.

As the story progresses, Laddy's transformation reaches a turning point when he is invited to a prestigious school event. Marge is excited for him, believing that this is the culmination of all her hard work. However, Laddy's old habits resurface as he struggles to fit in with the more refined crowd. He feels out of place and begins to doubt whether he truly belongs in this new world.

On the day of the event, Laddy's insecurities come to a head. He faces a choice: to embrace his new identity or revert to his old ways. In a moment of vulnerability, he confides in Marge about his fears and the pressure he feels to conform. Marge reassures him that he can be himself while still being polite and respectful.

Ultimately, Laddy decides to attend the event, but he does so on his own terms. He combines his rough edges with the social skills he has learned, creating a unique persona that impresses both his peers and the adults present. The event is a success, and Laddy earns the respect of his classmates, including Bart, who begrudgingly acknowledges Laddy's growth.

The episode concludes with Laddy feeling more confident in himself, having found a balance between his tough exterior and the social graces Marge helped him develop. Bart, while still competitive, learns to appreciate Laddy as a friend rather than a rival. The final scene shows the two boys sharing a laugh, solidifying their bond and hinting at a new chapter in their friendship.
