Lisa dreams of being honored as one of three great Americans, only to be waken by Marge's vacuum. Marge and the rest of the family have begun spring cleaning. Bart finds a box of old videotapes. He and Lisa start watching the tapes that are boring them, until Lisa finds a tape labeled "BART SAD." They put in the tape, which features an episode of Perfect Strangers and a commercial for a product that fights bad breath for babies. The baby featured in the ad is none other than Bart, leading Lisa to realize the tape should have been titled "Bart's Ad." The baby in the ad is referred to as "Baby Stinkbreath," which opens Bart up to name calling by his siblings. Bart confronts his parents about the ad and Homer tells him he was going to tell him on his "death bed." They tell him he enjoyed making the commercials and he made a lot of money that Homer invested in a college trust fund. Homer confesses that he used the money to buy back incriminating photos. Bart demands the return of his money; Milhouse suggests that he get a lawyer. He finds a lawyer and tells him he wants a divorce from his parents. In court, Judge Harm renders her verdict, Bart is emancipated and half Homer's salary is to go to Bart. Bart moves out and into a loft apartment. His first night alone he is scared by a rat and runs to the elevator that takes him up instead of down. The doors open to a loft apartment that contains skateboard ramps, "skate boarding legend Tony Hawk" and the band "blink - 182" playing live in the corner. The family comes to visit Bart at his new home, where Bart appears to be living the good life. Homer makes a plea for his return, but Bart tells them he is taking off for six months to go on the "Skewed Extreme Sports Tour." At the Springfield stop of the tour, Homer talks Tony Hawk into losing to him in a skateboarding contest so that Homer might win back Bart's affection. When Homer wins the contest, Bart informs him it wasn't about being cool, it was really about Homer not caring about how he felt. With a bit of advice from Tony Hawk, Homer makes an apology and gets a lucrative commercial endorsement for "Viagra-Gain" which allows him to repay Bart, who returns home.

The kids are getting ready to go back to school. On the first day, Principal Skinner holds an all school Spelling Bee, which Lisa easily wins, allowing her to go to the state spelling finals. If she wins there, she can then go Spellympics. Meanwhile, Homer has been trying Krustyburger's new "Ribwich" and enjoying it immensely. At the state Spelling Bee Lisa wins, but is disappointed with Homer who tells her that "very serious Daddy business" is going to keep him away from her celebration. Homer's daddy business consists of getting more Ribwiches. He is disappointed when the Ribwich is no longer available. Another Ribwich fan (and member of Ribwich Nation) informs Homer that the sandwich is going to be tested in other markets and he shows him the tour schedule. For a moment, Homer considers joining them on their bus tour. For her spelling efforts, Lisa is rewarded with a double-wide locker and she prepares for the Spellympics. At the Spellympics, Lisa makes it to the finals. Homer regrets that he won't be able to attend the finals, as he will be in San Francisco for the last day of the Ribwich. George Plimpton talks to Lisa about getting her to throw the spelling bee so that a more popular competitor can help keep spelling a viable sport. For throwing the bee, Lisa is offered a full scholarship to one of the seven sister's college of her choice. Lisa wrestles with her conscience. In San Francisco, Krusty stops by and tells the crowd they will no longer be making the Ribwich and he tosses them the last one. Homer catches it, and offers are made to him for the last one. He realizes that he's forsaken his daughter's big day for a sandwich and he trades it for a car, which he drives off to Lisa's big event. At the Spellympics, Homer arrives just in time for Lisa to do her final word. With her dad present, she blows the lid off of the rigged contest, but then misspells her word in the process. She loses the contest, but back home in Springfield she is celebrated as "the biggest winner this town has ever had." They even have her likeness carved into the side of a mountain.
