Task: Question Answering
Input (English): Franklin Bean is shown in flashback with his father, a postal worker at his high school. His poor performance is attributed to a lack of discipline which a school officials assures the elder Bean can be fixed with a stint in the Army. Then, in present day, PFC Bean is attending his father's funeral before returning to his duty station in Germany. In his state of grief he gets drunk, punches an MP and breaks through a plate-glass window in a local bar. Bean's army lawyer secures a plea deal, struck by his attorney Captain Ramon Garcia, in lieu of a court martial which involves him removing unauthorized tattoos from his hands (obtained during his drunken rampage), paying for a broken window and serving 90 days in the camp stockade. He is met at the gates by a decorated Korean War veteran Master Sergeant named Otis McKinney.  McKinney explains that the stockade is fairly small and, as a result, he is in complete charge of the compound while being supported by two guards; Corporals Harold Lamar and Gerald Gessner. Bean finds a sympathetic ear in stockade guard Corporal Lamar after learning he is just as afraid of McKinney and only "serving his own time." Gessner is a somewhat spineless lackey to McKinney whom he clearly admires and respects. 
Question: What is the last name of the person who gets drunk in a state of grief?
Output (English): Bean
