chunk: Two decades later, Mike (Matthew Perry), now thirty-seven years old, finds his life stalled. Scarlet (Leslie Mann), now his wife and mother of their two children, has separated from him due to his blaming her for his regrets about abandoning his future, forcing him to move in with his geeky, yet extremely wealthy, best friend since high school, Ned Gold (Thomas Lennon). At his job, there comes another reason for his frustration: due to his lack of higher education and since he is significantly older than most of his co-workers, he is passed over for a promotion he deserves in favor of a much younger worker. He quits his job and his high school-age children, seventeen-year-old Maggie (Michelle Trachtenberg) and sixteen-year-old Alex (Sterling Knight) want nothing to do with him. Later, while visiting his high school to reminisce, an encounter with a mysterious janitor (Brian Doyle-Murray) transforms Mike back into his seventeen-year-old self.
