Edited sentence: After a physical examination (which a somewhat hung-over Guthrie apparently passes without incident), Guthrie is sent for a psychological examination.Guthrie explains to the officer the story of the aforementioned littering incident, which was significant enough of a criminal offense to potentially disqualify him from military service.He is first sent to the Group W bench, where those draftees wait who cannot be inducted except under a "moral waiver", then outright rejected as unfit for military service.In an attempt to portray himself as insane, he indicates to the psychiatrist that he is homicidal, which (to his disappointment) earns him a commendation.The ironic punch line of the story's denouement is that, in the words of Guthrie, "I'm sittin' here on the Group W bench 'cause you want to know if I'm moral enough to join the army, burn women, kids, houses and villages after bein' a litterbug
