The 41–Year–Old Virgin Who Knocked Up Sarah Marshall and Felt Superbad About It

Andy, a 41-year-old virgin, shares a cramped apartment with his friends and struggles to advance in romance. He works a part-time job at a club as a failed stand-up comedian, while his friend Blaqguy suffers from Benjamin Button's Disease. The setup establishes his obliviousness to romantic advances and the comedic tone of his world.

Andy meets Kim at the club, and there is instant chemistry despite his awkwardness. She receives a promotion and abruptly leaves, leaving behind her false leg. The moment foreshadows potential romance but is interrupted by real-world consequences.

In a bid to help Andy lose his virginity, his friends stage a series of over-the-top schemes during a poker night. The plans are well-meaning but chaotic and repeatedly backfire. The scene sits at the center of the group’s prankish dynamic.

Andy meets Sarah Marshall and is drawn to her awkward charm, but nerves lead to a vomiting incident in his car. He tries to sleep with her, only to be deterred, and then returns after encouragement from Seth. A chaotic pub brawl erupts when Blaqguy is involved with Sarah, ending with Andy covered in feces.

The next day Sarah arrives at Andy's apartment claiming she is pregnant and that the child is his. He denies paternity, causing her to leave in a burst of emotion. The revelation shakes Andy's sense of certainty and sets off a new course of events.

Seeking an escape, Andy takes a vacation to Hawaii and reconnects with Kim, who is now a hotel manager. He learns that Sarah and her new boyfriend Aldus Snow are staying in the room next to his. The trip blends romance with awkward entanglements that continue to complicate his love life.

Andy goes on a date with Kim, and their attempt at intimacy is interrupted when Sarah materializes, leading to a heated fight. Both Sarah and Kim ultimately leave Andy, highlighting the fragility of his romantic progress. The incident deepens his sense of instability and confusion.

In a surreal dream-like sequence, Andy encounters Mace Windu and Yoda and contemplates that virginity might extend his life and grant force control. He ultimately rejects the idea after learning his scrotum would inflate in size. The moment blends fantasy with his ongoing quest for control over his fate.

Andy reconciles with Kim after a near-miss that culminates in her being struck by a car. They marry soon after, turning their unstable romance into a committed relationship. The wedding marks a new chapter despite the chaos that frames their lives.

On their wedding night, they consummate, and Andy's semen is so forceful it blasts Kim through a window. This triggers a chain of worldwide events, including wildfires in California, floods in Louisiana, and a thwarted missile attack by Kim Jong-il. The consequences extend far beyond the couple's relationship.

Meanwhile, Jonah, Michael, and their friend McAnalovin' drift through a string of misadventures. After being pulled over for using a false ID to buy alcohol, McAnalovin' embarks on a Grand Theft Auto–style escapade that backfires spectacularly. His actions unwittingly unleash an army of Mexicans, escalating chaos.

Jonah becomes separated from the group and is briefly accused of pedophilia after an encounter with Chris Hansen. The accusation complicates the escape and adds a dark, farcical twist to the subplot. The misadventures contribute to the film's chaotic energy.

Jonah and Michael regroup and travel toward Hawaii in the car that previously struck Andy. They are slain by the Mexican force, collapsing their arc in a final act of chaotic tragedy. The journey ties back into the larger spectacle of the story.

Michael has fallen in with lactose-intolerant vampires led by Edward Cullen, adding a parody of vampire lore to the ensemble. The oddball subplot broadens the film’s surreal humor. The thread converges with the film’s chaotic energy rather than a conventional resolution.
