Stealing First Base

Bart's fourth-grade class is merged with another fourth-grade class when teacher Mrs. Krabappel is absent. In the crowded classroom, Bart is forced to sit by a new student named Nikki. At first, they dislike each other, until Nikki admires Bart's artistic skills. Bart seeks romance advice from Homer, who passes him off to Grandpa Abe. After Grandpa advises Bart to kiss Nikki, however, when Bart does so after the two skateboard together, she recoils in disgust. Nikki's attorney's parents threaten to sue the school unless it is declared an "affection-free environment". Superintendent Chalmers causes a play in which Willie plays Nikki and Skinner plays Bart who was strangled by Homer after calling him a “Fatso”, meaning they are forced to kiss. Bart is confused at the outcome of this seemingly innocent action, and his confusion is later amplified when Nikki hides in his locker and kisses him again.

Meanwhile, Lisa becomes popular when she receives an F on a test, but becomes unpopular again when it is revealed that her test was mistakenly given to Ralph, as both tests were mixed up as the F grade was supposed to be given to Ralph who had written Lisa's name on his test. Angry about being ostracized for being an overachiever once again, Lisa blogs about it, and her post is noted by a mysterious blogger known as Flotus 1 who turns out to be First Lady Michelle Obama. Obama drops by Springfield Elementary to give a speech about the importance of academics and recommends that the students should be nice to Lisa and other overachievers like her friends, Martin Prince and Allison Taylor.

Bart and Nikki have been watching this speech from the roof, and Bart confesses to Nikki he does not understand her ever-changing moods. They argue and Bart stumbles, falling off the roof. Nikki says "I love you," but seeing that Bart is breathing treats him badly again. Bart stops breathing again, but the school's "no-touch" policy prevents anyone from performing CPR. Nikki defies the policy and revives Bart via mouth-to-mouth, thus setting off a montage of kiss scenes from various movies, some of which (such as Alien 3) never even had kiss scenes in them. When Bart awakes, Nikki's mood changes yet again and Bart remains in a state of complete confusion over female behavior. He tells her he does not care what happens between her and him, but then changes his mind and yells out "I love you!" after she kisses him once again.

Throughout the episode, Nelson Muntz has befriended a blind boy and teaches him how to laugh at the misfortunes of others. In the end, the blind boy tricks Nelson into believing that a punch he sustained after insulting Nelson restored his sight. When he reveals to Nelson that this was a prank and laughs at Nelson's signature "haw haw", Nelson is as impressed as he is touched by the achievement.

The episode is written by John Frink and directed by Steven Dean Moore, his second director credit for the season after "O Brother, Where Bart Thou?". The episode features guest star Sarah Silverman as Nikki (Bart's crush) and Angela Bassett as Michelle Obama.[2]

In September 2016, executive producer James L. Brooks told Variety that the crew had been "aggressive" in trying to get Obama to voice herself, and received a rejection note saying "good try".[3]

In the classroom, Nikki shows Bart a book about vampires which looks like the Twilight series book New Moon, which reads Red Moon. In the scene where Nikki performs CPR on Bart, recreations of kissing scenes from a variety of films and television shows are shown. These scenes are (in order); From Here to Eternity (1953), Gone with the Wind (1939), The Quiet Man (1952), Lady and the Tramp (1955), Planet of the Apes (1968), On Golden Pond (1981), Ghost (1990), Spider-Man (2002), Star Trek (2009), Beauty and the Beast (1987–1990), The Public Enemy (1931), WALL-E (2008), Alien 3 (1992), The Godfather: Part II (1974), and an All in the Family (1971–1979) episode in which Sammy Davis Jr. guest starred. The sequence, and the accompanying musical score, are a nod to Cinema Paradiso (1988), directed by Giuseppe Tornatore, with score by Ennio and Andrea Morricone.[4] The Itchy & Scratchy cartoon is a parody of the 1982 film Koyaanisqatsi: Life Out of Balance, here titled Koyaanis-Scratchy: Death Out of Balance.[5]

The scene where Bart and Nikki were performing a skateboard parkour contains the song "Chase" by Giorgio Moroder on the original FOX broadcast. When the episode is shown in syndication, "Chase" is replaced by a musically similar composition.

The classical music that is heard during the montage of movie kiss scenes is from Cinema Paradiso - "Love Theme", composed by Andrea Morricone.
