U.S. soldier Douglas, taken prisoner in the Vietnam War, deliberately played the total idiot. Guards thought he was useless and let their guard down; while cleaning he memorized the names and locations of over 250 fellow prisoners. Released early in 1968, he passed the intel to the U.S. military and saved hundreds of lives. History's smartest "idiot" 😱
