Hey! My Dad went to the 1939 worlds fair! Told me that he saw the first television device in his life there...
but he waited until 1944 to get his Lugers, taken from a couple of German soldiers he was interrogating (somewhere in Belgium if I remember correctly)... He said one of the Germans had been educated in the USA... spoke perfect English... but was very reluctant to give any information ... until my Dad threatened to shoot him with his own pistol!
Then he had a change of heart...
You can't get away much with that kind of behavior any more... Dad never told me if he really would have shot him... but you had to know my Dad to understand that when he spoke, you could never tell if he was joking... He could have sold sand to the arabs... what a POKER FACE.
