Offset by the disappearance of Brian and Stewie, the lost pair continues with their adventures. The next day, while driving Stewie to Gymboree Play & Music for parachute day, Brian decides to take a detour to the recruitment office to scold the recruiting officer for trying trick Chris through devious means. The two arrive at the office but the wait is long; when Brian goes to top-up the parking meter Stewie walks into the office. Stewie ends up enlisting in the Army and signs Brian up as well when told there "is a $100 BONUS for signing up a buddy." Brian returns and is shocked. Brian and Stewie begin basic training, but Brian becomes stressed from the discipline and decides one night to leave. Stewie wakes up and finds Brian packing his suitcase, but he manages to talk him out of leaving, insisting that he had never finished anything significant in his life and that the Army will provide him the discipline. With this, Brian decides to stay. After they complete their training, Stewie and Brian are deployed to Iraq. Meantime, the two are patrolling the streets of a village, commenting on the "good situation so far"; however, after the pair get caught up in a terrorist attack, they become dissuaded and decide to find a way to get out of the Army. They first attempt to be discharged by pretending to behomosexual (only to discover that one of their superiors is gay). As a last resort, they attempt to get "Wounded in Action" by shooting each other in the foot; they do this only to find out that the Army now takes anyone no matter what, going so far as to allow two corpses to guard the ammunition. They are then told that democracy has kicked in and the war is over, thus meaning all the soldiers can return to the United States. Meanwhile, to distract Chris from the Army, Peter takes him to look at extracurricular activities at his school, where he is accepted into a heavy metal band. Chris develops a rebellious and rude attitude after joining the band, and he significantly changes his appearance. Peter and Lois, worried about his behavior, search his room to find the cause of his behavioral change; Lois becomes convinced it is a result of listening to the violent lyrics from his music. In addition, they find a poster shrine to Marilyn Manson in his closet, and become convinced that his music corrupted their son. They decide to track down Manson and find him at the Grammys Music Awards. When they find Manson, Peter punches him in the face and Lois accuses him for destroying their son with his songs. Manson, played by writer Tom Devanney, laughing at "this old thing again", offers to help them with Chris. Manson returns to the Griffin house with Peter and Lois, where he tells Chris and his bandmates that it is important to respect and obey their parents, and in addition to mending the tension between them, Manson ends the episode by giving Peter some more parental advice: Peter and Chris should start fishing.
