Marge invites an old pen pal to stay with Homer and cross items off his "to-do" list from when he was 10 years old, so that Homer can embrace his "You-Only-Live-Once" spirit. Meanwhile, Lisa starts an honor code for the school to combat cheating.

After a night of playing poker with Moe, Lenny, and Carl, Homer finds himself in an elevator with a young mother named Gretchen, who is in labor and needs someone to help her keep calm. Meanwhile, Lisa helps the local football cheerleading team unionize and negotiate for better wages and working conditions.

Lisa makes friends with a new girl in school, who turns out to be a conservative Republican (a George W. Bush one rather than an Abraham Lincoln or Ronald Reagan one) with connections to Springfield's Republican party.

When Principal Skinner promises that the most well-behaved at Springfield Elementary will get to ride in a submarine, Bart does everything possible to become a model student. Meanwhile, Krusty, on Lisa's advice, sells the foreign rights to his show in order to rake in more money, but the international Krustys soon become more popular than the domestic ones.

To combat the poor quality of today's movie theaters, Homer and Bart begin to illegally download movies and exhibit them in a makeshift theater in the backyard, but Homer ends up arrested when Marge sends the FBI a check and an apology note.

The Comic Book Guy falls for a Japanese manga artist, but Homer's advice and the woman's father may ruin his chances at true love.

Mr. Burns gives his workers Google Glass-style computer glasses so he can spy on them, but Homer gives the glasses to Marge, and discovers that Marge has been going to therapy to discuss her life. Meanwhile, Nelson bullies Bart into giving him the best Valentine's Day gift ever.

Bart makes friends with a transfer student named Diggs, an expert in falconry who saves Bart from the wrath of the Springfield Elementary bullies – and who intends to take to the sky himself, which makes Bart worry about Diggs' sanity.

Lisa discovers that Sideshow Bob has become the chief scientist of a massive chemical engineering company, but the two of them bond over their appreciation for high-culture. Meanwhile, Marge ends up a church volunteer to help horny teenagers become abstinent.

When the Retirement Castle is closed for health violations, Marge invites Grampa and two other old people to live at the Simpsons' house, only to get frustrated with Homer embracing the "old person lifestyle". Meanwhile, Bart defends Nelson's decision to wear his mother's underwear, and ends up part of a bully gathering a la The Warriors.

Marge buys a painting at a yard sale. She decides to auction it off when it appears to be valuable, but it turns out to be a forgery.

At the school assembly, Principal Skinner presents a skit about living history. The kids begin heckling them and the assembly devolves into a disaster. Chalmers suggests holding a speech contest on the students' heroes. After Martin beats her to the punch using her first idea, Marie Curie, Lisa changes her speech to one on Homer. Lisa wins over the crowd and both kids' speeches are posted online. Lisa's goes viral, so much so that Homer is called to referee games in the World Cup in Brazil.

Back at school, Lisa sees a boy choking on pizza. She performs the Heimlich maneuver on him, reveals his name is Lucas Bortner and he's a competitive eater. She doesn't think that competitive eating is for him, and suddenly gets a crush on him. She then thinks about changing him. Meanwhile, Snake, grateful for Bart's actions, steals a PlayStadium 4 and leaves it in Bart's room.

A sequel to "Future-Drama" and a continuation of "Holidays of Future Passed," set 30 years from now. In this futuristic installment, Bart goes to a clinic to rid himself of his feelings for his ex-wife Jenda (who is now dating a xenomorph-esque alien named Jerry), Lisa must choose whether or not to cure her zombie husband Milhouse after he gets bitten by a homeless zombie, and Marge (after putting up with years of Homer dying and being cloned back to life by Professor Frink) loads Homer onto a flatscreen monitor and throws him out of the house.

Bart makes a voodoo doll of his hippie art teacher when he gets sick of art class and cast a spell to make her sick, but when he inadvertently gets her pregnant, he becomes a savior to Springfield couples trying to conceive - and is subsequently kidnapped to help conceive a thoroughbred race horse.

Marge swears off befriending any more couples when Homer offends their charming new British neighbors. But when Lisa declares that she, too, doesn't need friends, Marge reconsiders.

Bart is plagued with guilt when he wins the annual "last day of school" race around Springfield Elementary, with an assist from Nelson, who beats up frontrunner Milhouse. Meanwhile, Homer tries to bring back the annual 4th of July fireworks display after it's canceled for budget reasons.
