Last names are more funner, there is no escaping them. Consider these actual folks who, knowing their names, still chose to join the navy. There was seaman Seaman, later rated as a Boatswain's Mate. BM3 Seaman get over here! Hilarity ensues. It's always been a naval joke, but I saw the real guy. If your last name is Cox, why pray tell do you decide to be an Interior Communications specialist? Then there was seaman Hard, a constant fount of jokes.
