A little story from Battle of Britain..

One day... One Spitfire pilot, Geoffrey Page, who was badly burned when his plane was hit and set afire by an Me-109, managed to open his parachute though his hand were fried to the bone. The flames had destroyed his uniform and scorched his face and body, and he wallowed in the water half-naked an in great pain, dimly sensing that a boat was circling him. Finally, through the agony that racked him, Page heard a voice calling out: "Who are you___a Jerry or one of ours?" It took Page some time to spit out sea water and cry back through his cracked lips: "Stupid f------ bastards, pull me out!" The boat immediately pulled up alongside him and strong arms reached out to lift him aboard. "The minute you swore, mate," one of the crew said, "we knew you was from the RAF."   (from WORLD WAR II, TIME | LIFE BOOKS)
