Sean's takes a swing at tree surgery and ends up causing a blackout during the superbowl. But his biggest concern is what he saw through Lily's window while chopping the tree -- Lily holding a bag of pot. But what's even more shocking is where Lily got the weed: out of Sean's closet. With the blackout, Dan O'Keefe moves his Superbowl party to the Finnerty home, where they listen to a play-by-play given by Jimmy from his 5-inch TV.

Sean accepts a challenge from his obnoxious neighbor, Mr. O'Keefe, for a boxing match. But he has second thoughts when he discovers Eddie's tried to fix the fight. Meanwhile, Claudia becomes enraged when she learns about a rumour that she's had breast enhancement surgery.

Sean joins the Knights of Hibernia in order for Lily to compete in their beauty pageant.

After Sean confronts Brad's father, who's boasting that Lily and Brad have slept together, he confronts Claudia -- and finds out she already knew too. So when Brad mysteriously gets injured by an airborn Christmas decoration, everyone thinks Sean finally lost his temper. Meanwhile, the boys have spent Sean and Eddie's Liberty quarter collection, and Eddie is disgusted. So Eddie takes the boys out to teach them a lesson about stealing from other people -- by stealing a toy machine that Henry loaded with quarters.

Claudia feels it's time to smooth relations between the two families by having the O'Keefes over for dinner, but the evening falls apart when Brad's mother blames Lily for taking Brad's innocence. Meanwhile, Eddie teaches Jimmy and Henry a lesson in respecting other people's property after he finds out that they used his coin collection to play arcade games.

Brad's (Bret Harrison) dad, Dan (guest star Gregory Jbara), claims to have been taking tennis lessons for years, however, after Sean (Donal Logue) beats him at a tennis game, it is revealed that Dan has been having an affair and not taking lessons.

When the Finnerty's throw Brad a birthday party to take his mind off his parents' recent breakup, Sean secretly invites Brad's dad to the party as part of his ""plan"" to reunite him with his wife Connie (guest star Nancy Cassaro). Unfortunately, Connie has taken Claudia's (Megyn Price) advice to ""get some,"" which prompts her to pursue Eddie.

Sean becomes infuriated after receiving letters from the Home Owner's Association telling him to clean up his house, while Claudia is happy about the positive changes to the neighborhood. Meanwhile, Lily insists that Brad buys her an anniversary gift from a list that she's made... but he defies her wishes and gets her a sexy nighty... that he can't enjoy because he's busy picturing Sister Helen, who he ran into at the lingerie store. And Jimmy shocks the family by making an unusual lifestyle choice -- he announces that he's a vegetarian.
