Under the neon glow of an alien thrift store, Rick haggles with a tentacled shopkeeper over a broken "antimatter resonator," while Morty, his eyes drawn to a life-sized robot with a provocative design in the corner, can barely contain his fascination. The elementary schooler—still mastering addition within ten—pleads relentlessly until an exasperated Rick gives in: along with the resonator, the robot labeled "Made on Gazorpazorp" is packed up and brought back to Earth. No one could have predicted that this robot, which Morty secretly names "Gwendolyn," would give birth to a gray-blue, horned alien baby that very night, turning the Smith family's life upside down.
"Don't name it!" Rick snaps, aiming an ion gun at the squalling infant in the bassinet, his voice cold with scientific disdain. "Male Gazorpazorpians are born with a destruction gene—this thing will grow into a war machine in a day." But Morty, blindsided by his sudden "fatherhood," clings to the baby defensively. "I already messed up by not being careful," he argues. "Now I need to learn to be responsible." He stubbornly names the child "Morty Jr.," and Beth and Jerry's reactions lay bare their own parenting flaws—Beth tries to recite behaviorist mantras like "Crying won't get you rewards" to the baby, while Jerry can only awkwardly agree. The family ultimately decides: let Morty try raising this unusual child himself.
As Morty embraces his role as a teen dad, Rick, determined to uncover the robot's origins, takes Summer—who's been complaining about being left out of adventures—through a portal to Gazorpazorp. The planet's surface is teeming with primitive, fur-covered male aliens wielding stone axes, who lunge at Summer the moment they spot her, seemingly confirming Rick's claim that "male Gazorpazorpians are violent and aggressive." But a sudden landing of a massive spaceship shatters this perception: the vessel lifts the pair into the sky, revealing a highly advanced society built by female Gazorpazorpians, who wear matching uniforms and control the entire planet via holographic projections.
The truth behind this matriarchal society is shocking: after an ancient gender war, female Gazorpazorpians broke away and began manufacturing sex robots to send into the universe. Once the robots conceive, the females retrieve them—keeping baby girls to raise with higher education, while ejecting baby boys onto the surface to fend for themselves. Thinking on her feet, Summer poses as an aristocrat and claims Rick is her "lowly manservant," temporarily gaining their trust. But Rick's chauvinism eventually gives him away: he lets out a loud fart during a solemn council meeting, deemed the ultimate insult to female authority, and is sentenced to death on the spot. In a desperate bid for mercy, Summer points to her crop top and argues, "This shirt was designed by a man—men on Earth aren't all violent idiots." The absurd yet compelling defense actually persuades the female rulers, and the pair are allowed to return to Earth in an escape pod.
Back on Earth, Morty Jr.'s growth rate defies all biological logic. As an infant, his first word isn't "daddy" but "death," followed by violent terms like "damnation" and "destruction." Morty tries to guide him with children's shows, only to find that Morty Jr.'s drawings are all gory scenes of murder. Desperate to prevent his son from causing chaos, Morty lies and tells him, "The air outside is toxic," locking him indoors. But when the adolescent Morty Jr. discovers the truth, his repressed destructive urges erupt—he storms out of the house, flipping cars and smashing store windows, becoming the "disaster" Rick had predicted.
Rick and Summer's return escalates the standoff. Rick raises his ion gun again, but Morty steps in front of the weapon, shielding his son. "He just needs guidance, not destruction," he insists. Morty takes the enraged Morty Jr.'s hand, recites the melody of a children's song they once listened to together, and admits his own inadequacy: "I'm a first-time dad too, just like my parents were when they raised me." At that moment, passing cartoonist Brad Anderson stops to share his own experience of channeling violent impulses into creative inspiration. His words resonate with Morty Jr., who looks at his awkward yet sincere father and finally lowers his fists.
The episode ends with dark humor. Morty Jr. moves out and becomes a New York Times bestselling author with his memoir My Terrible Father, turning his childhood trauma into creative material during a TV interview. Meanwhile, Morty smiles faintly as Beth comforts him back home. Rick leans against the couch, sipping a drink, and teases Summer: "No more adventures with you—you're more trouble than Morty." But his eyes hold less of their usual coldness. Outside, under the night sky, this chaotic family has each grown through their absurd adventure—Morty learns the weight of responsibility, Summer proves her wisdom, and Rick may finally begin to understand that blood and emotion are far more complex than cold scientific formulas.
Through its dual narrative, the episode tears away the facade of gender and parenting: the gender divide on Gazorpazorp is an extreme parody of real-world sexism, while the father-son conflict between Morty and Morty Jr. debunks the myth that "parents are born knowing how to love." As Beth admits, "When I raised Summer, I just let her cry until she fell asleep"—every parent is a clumsy beginner, and love and tolerance are the ultimate answers that transcend species and blood.
