He is employed, on a part time basis only, as a toll booth collector. His best friend is a kind-hearted delivery guy named Nazo (Rob Schneider) who stops by every so often. Sonny also has a habit of frequently harassing his roommate's girlfriend, Corinne (Leslie Mann) about her previous employment at Hooters every chance he gets.

Two of his male friends from school, in contrast to their conduct in Sonny's experience while at school, are now revealed to be homosexual and in a committed domestic partnership.

Kevin is revealed as having fathered an illegitimate son, whose name is Julian (Dylan and Cole Sprouse). Julian is abandoned at Sonny and Kevin's apartment, with a written explanation that Julian's mother is now declining to care further for Julian. It is revealed at the Social Services office that Julian's mother died of cancer. Kevin, at the airport ready to go to China, gets a call from Sonny informing him of the letter and the boy. Sonny decides to handle the situation himself and in the process decides Julian will solve his problem with his ex-girlfriend. His plan backfires and ends up at child services trying to give Julian back. Rather than give Julian to a foster home he decides to hangout with Julian until a new family is ready for him. Sonny, in caring for Julian, soon discovers a new purpose in his life and a deep connection with Julian as a father figure. But social services discovers that Sonny is posing as Kevin, and insists that he give up Julian. Social services takes Julian and decides to press charges against Sonny. The case is brought to court, where Sonny has his friends as counsel, including Layla (Joey Lauren Adams), Corinne's sister and Sonny's new girlfriend; and late-arrivee Kevin. Despite positive testimony from his friendseven Corinne, who swore to disliking him from the day they metand changing the opinion of his own father, also a prominent attorney, the judge is ready to sentence him to jail for kidnapping Julian and defrauding the state. At this point, Kevin steps forward as Julian's father and insists that no charges be filed, having remembered a drunken fling with a Hooters girl in Toronto during the 1993 World Series, and connecting that with Julian's earlier testimony of originally coming from Toronto and being born in July. The judge grants custody to Kevin to the dismay of Julian, who wants Sonny as his father. Sonny tells Julian that can never happen because his real father is present, but they can be friends. Sonny moves in with Nazo while Kevin gets to know his son. One year, three months, and six days later, Sonny, now a lawyer and married to Layla with a child of their own, is surprised with a birthday party at Hooters attended by all his colleagues and friends, including Julian, but is more surprised to find his ex-girlfriend working as a Hooters girl and her boyfriend with his so called five-year plan working the grill.
