The hour-long variety special presents itself as one episode of a larger series. The special consists of several songs, skits, and activities interspersed with scripted segments of Mulaney chatting with the Bunch as well as unscripted interviews with both the children and the adult guest stars about their greatest fears and acting background. • As an ensemble, Mulaney joins the cast to perform the opening sequence to the show ("It's John Mulaney & the Sack Lunch Bunch!"). It is reminiscent of classic childhood television opening themes. • Jake, appearing as a younger version of Mulaney, sings a song ("Grandma's Got a Boyfriend") about his grandmother's boyfriend, Paul, and his many quirks, while wondering why the rest of his family hasn't accepted Paul. • Jonah summarizes a fictional book he has read called ''Sascha's Dad Does Drag and the Act Needs Work'', a book that features a comically frank depiction of drag culture from the perspective of the son of an aging
drag queen. • Mulaney plays the producer of a fictional
Sony Pictures Animation film called
Bamboo 2: Bamboozled which is being focus-grouped by the entire Bunch. The skit pokes fun at the kids' viewing habits and the tropes of modern western animation. • A father, played by Mulaney, hires a math tutor (
André De Shields) to help his son, Jonah, with algebra. The Tutor performs an elaborate Dixieland-style jazz number ("Algebra Song") about how not knowing math caused him to lose his eye — however, it turns out to be a
shaggy dog story, with his eye being
unexpectedly saved at the last minute. It is later later revealed that the Tutor lost his eye by accident while performing the song. • A transitional scene focused on Googy, presented as a recurring
Sack Lunch Bunch character, is interrupted when Mulaney is forced to reveal to the kids that the actor who played Googy died, subsequently having a frank conversation about death. • During lunchtime, Orson breaks into song about how he will only ever eat one food: "a plain plate of noodles with a little bit of butter." • Mulaney and Tyler play a chess game and continually try to throw one another off with existential questions and absurd facts. • Suri urges Mulaney to play "restaurant" with her, only for the game to end abruptly when Suri refuses to allow him entry into her imaginary restaurant. • Actor
Richard Kind has an unscripted discussion with Ava, Cordelia, and Camille about movies, his career, and their experiences in plays. Nearly every sentence contains the phrase "girl talk." • Lexi and her friend
David Byrne prepare to put on a skit in front of the guests at her parents' dinner party. However, when all of the guests talk over the performance, she and Byrne launch into a musical number urging the guests to pay attention and explaining what they planned to do in the skit, including cartwheels, acting out the entirety of
Frozen, and a fake newscast
while wearing an enormous blazer. • Zell and Oriah perform a dramatic '80s-inspired
power ballad wondering what happens to flowers at night. • Jacob and David Byrne make a
papier-mâché volcano despite Byrne's childhood fear of volcanoes. • While Mulaney asks about the Bunch's top New York moments, Alex recalls a time he was in New York and saw a woman (
Annaleigh Ashford) crying on the street. He wonders in song about what would happen if he had gone up to her and asked what was wrong, and imagines the friendship they may have shared if he had done so. • Special guest Mr. Music (
Jake Gyllenhaal) attempts to demonstrate how one can make music without instruments. However Mr. Music, having failed to prepare for his segment, grows increasingly exasperated as the objects around the studio he tries to use as examples fail to make any sound. • The special ends with a final round of interviews with all of the child and adult performers. == Cast ==
