Buster in the United States Army at the urging of a Michael Moore impersonator. Although Buster's training is poor, his possible deployment to Iraq is a recurring fear of his and his mother's. This possibility is abruptly nullified when Buster's left hand is bitten off by a "loose seal" (pun on "Lucille"), when he impulsively gets the courage to jump into the ocean one day after years of being afraid to swim. In subsequent episodes he wears a trans-radial prosthetic on his left arm that is sometimes a hook and other times a prosthetic hand. In season 4, Buster reenlists in the Army for a sense of purpose after his mother Lucille is arrested and Lucille Austero rejects him for being unable to have a relationship rather than view her as a surrogate mother. In the Army, Buster is unwittingly made a UAV pilot (thinking he is merely playing a video game), but is "wounded" after falling out of his chair, receiving several commendations and being fitted with an oversized robotic hand that makes more powerful motions than he can control. Realizing for the first time that he has been killing people as a UAV pilot, he fakes failing his physical therapy, eventually failing the "Q Test" (cute test) in which he proves he is able to control his prosthetic when he delicately holds a kitten. After being discharged from the Army, he meets Herbert Love's wife, Ophelia, who takes pity on him and convinces her husband to let him stay with the family, suggesting he could be useful to the campaign as a poster child against wasteful government spending. She later sleeps with Buster in retaliation for photos she finds of Herbert and Lindsay, but then breaks it off with him after Herbert ends his affair and wants to make the marriage work. At Cinco de Cuatro, Buster knocks Herbert unconscious with his prosthetic hand after being told by Perfecto Telles (an anti-bullying squad member defending Maeby) that Herbert is a bully. His storyline in the fourth season ends with him being arrested for Lucille Austero's murder after being seen around the staircar where her body went missing. In season 5, Buster is arrested for the murder of Lucille Austero. He participates in a float parade participating as an inmate. Oscar breaks Buster out of jail by escaping from the parade and leads Buster to believe that this is
