Lisa Simpson, This Isn't Your Life

Plot

Maggie is upset because she missed out on a collectible Happy Little Elves toy on the final day of a promotion. To fix this, Homer takes the family to the gas station running the giveaway. He keeps buying gas in hopes of getting the rare "Baby Must Have" figure, but he fails. On the way back, they drive through the neighborhood where Marge grew up.

While looking at her mother's old house, Lisa finds out that Marge was an honor roll student. Lisa asks Principal Skinner, who confirms Marge was smart but says that didn't stop her from becoming a stay-at-home mom. Skinner warns Lisa that she will probably end up the same way, because he believes children often repeat their parents' lives. Meanwhile, Bart is doing a stunt on the school playground and gets mud all over Nelson.

When Nelson tries to punch him, Bart slips and accidentally kicks Nelson in the face. The other kids then see Bart as the new school bully. Lisa learns that Marge's grades dropped sharply after she met Homer, and she decides not to let herself get distracted. She clears her room of anything that could take her focus away from her goals, including her saxophone.

When Marge realizes Lisa wants to be nothing like her, she becomes cold toward her. At school, Nelson confronts Bart at the tetherball pole and swings at him. He misses and hits the ball, which swings back and hits him by accident. Later, in the hallway, Nelson walks into a locker and gets stuck inside.

Lisa hears about Cloisters Academy, a fancy school, and tries to convince her parents to let her go. Marge says no because it costs too much. After the principal and Marge talk about Lisa's record, Lisa is offered a scholarship. Following Marge's advice, Bart stops Nelson from attacking him by making Nelson feel good about himself, ending their fight.

Lisa then finds out she didn't actually get a scholarship; she was accepted because Marge agreed to do the school's laundry. Worse, Marge has become exhausted from all the work.

Lisa tells Marge she no longer wants to go to Cloisters, calling it "too elitist," and says she would be proud to be like her mother. But she hides a guilty expression from Marge. Meanwhile, Homer steals a "Baby Must Have" from the gas station to make Maggie happy.
