It's a way of handling stress. Laugh it off! WW II Germany Nurses and teenage boys drafted to help are helping unload wounded from an ambulance train that just arrived from the Eastern Front. One youth recalled an incident between injured soldiers and nurses: A "walking wounded" with his right arm missing shouted, "Hey sister, I am right-handed. How do I wipe my a**?" "You are right handed? Use your right foot," said one of the nurses. Everyone still conscious laughed. "You think that's possible?" "Listen," she replied, "the Fuhrer said, "For a German soldier, nothing is impossible.' Nothing!" Again wild laughter, soldiers' gallows humor.
