When he gets tired at a party, he becomes a drag on Lois and she splits off to party with younger girls. Peter complains about her behavior back at home. On television, a report regarding Justin Bieber shows Lois hanging out with teenage girls. Lois then sneaks into the concert with intentions to seduce Bieber but Peter bursts in and beats the tar out of him. After Peter demands that Lois come home, she refuses, and brings up the names Peter called her. After Peter apologizes for acting like a jerkass, he admits that he really likes Lois for who she really is. When Bieber is called back onstage Peter is forced to go out and substitute “Conway Bieber.” Back home, Peter recites his love for Lois, but messes up her age.
