After his wife leaves him, Ben tries to get back into the dating scene while making time for Luke, who's more interested in girls than in dad's idea of fun. The culture clash is exacerbated when Seamus calls from Ireland to announce that he's visiting. While at the airport to pick his dad up, Ben meets Madeline, who recognizes him as the famous architect and gives him her card. Ben brags to his friend and partner, Alex, that a woman gave him her card. Alex and receptionist Wendy beg Ben to hurry up and call her already before she loses interest. But Ben discovers he lost her card and decides to forget it -- until Madeline calls him and asks him to dinner. Ben suddenly remembers that the date he just agreed to coincides with his taking Luke out to ""The Lion King"" musical. Alex and Wendy won't let Ben stand Madeline up, so Ben gets Seamus to take Luke. But Luke angrily cancelled a date of his own for his father -- and didn't want to go to ""The Lion King"" in the first place. At dinner, Be

Ben is rattled when he sees Luke playing basketball with Serge, Vonda's new boyfriend, right after telling his pop he was going to a friend's. Ben has the Serge talk with Luke, and learns that Luke asked Serge to play with him in a two-man tournament -- which happens to be a father/son game. Luke just wants to win, but starts to take Ben's feelings into consideration. Vonda calls Ben to lay some blame when she learns that Luke dropped out of the game with Serge. Ben begins to question his usefulness as a parent, so he meets with Vonda to clarify why Luke dropped out. Then he decides to get more involved in Luke's life by taking Serge's place in the game -- even though it's that same night. Luke is worried that Ben is going to humiliate him, but goes ahead with it anyway because of Seamus. After a chat with Seamus, Ben begins sharing the same fear as Luke, after which he bails out and lets Luke reinvite Serge. But when Serge ends up getting them disqualified, Luke makes amends with Ben

Ben learns that the pub's bartender has been deported, and reminds Seamus that if he wants to stay in the country, he should check up on the status of his visa. Seamus decides to write down his memoirs to impress the I.N.S., just in case he does choose to stay -- even though Ben doesn't necessarily want him to. Alex and Wendy suggest Ben let Seamus' visa expire quietly, so he can get kicked out. But a guilt-ridden Ben goes down to the I.N.S. to inquire about his father -- only to find out that his visa has already expired. Since Seamus is mad at Ben for wanting his space back and possibly getting him deported on purpose, he goes to stay with Alex. Ben reads Seamus' memoirs (which are more depressing than Angela's Ashes), and changes his mind about wanting Seamus to leave. Ben then lays down some ground rules and agrees to sponsor Seamus, so he can stay in the country until he gets citizenship.

When both Seamus and Luke run dating circles around Ben, Wendy decides to offer her matchmaking services to him. But Ben doesn't want to go out with Wendy's blind date, who's a dermatologist and, like Ben, isn't looking for a serious relationship. He does want somebody to check out a mythical freckle of his, though. After sharing his news with Seamus and Luke, Ben goes to Wendy's dermatologist, Dr. Ivy Castelli, for his ""checkup."" The next day at the office, Ben admits to Alex and Wendy that he and Ivy slept together. And worse, he let ""I love you"" slip out. Confounding the problem is a gift basket Ivy sends to Ben that returns the sentiment. Ben pays a visit to Ivy's office to clarify what he said, and how he still isn't looking for a serious relationship. Thus ends Ben's 24-hour office visit. Meanwhile, Alex pesters Wendy to fix him up with somebody, so she gives him her therapist's number.

Ben and Alex meet New York's ultimate bachelor, Sebastian Jones, whose swanky apartment they're renovating. Believing he gets it regularly, an awestruck Alex puts on a cool face to impress the guy, while Ben won't initially admit to feeling sexually inferior -- even after Sebastian mentions his invitation to Fashion Week, and how he can't go this year. But an insensitive comment from Luke about how Ben has no life changes his tune, and he and Alex return to Sebastian's apartment to get the invitation and go to Fashion Week in search of coolness. Before they leave, two of the models, Kim and Jade, drop by to see Sebastian, and Ben and Alex decide to use the chance encounter -- and the invitation -- to make a move on them. The bouncer, Jake, lets Kim, Jade and Ben in, but won't let Alex in because he finds him too ""eager."" Ben comes back outside to tell the bouncer Alex is with him, but instead of getting Alex in, Ben gets himself out. Later at the pub, Ben decides that sort of bachelor'
