A grandfather is telling his grandson war stories.
“At the end of World War 1, I was awarded for my bravery after saving a group of my men,” the grandfather says. “You see, we were fighting in northern France and one of our enemies threw a grenade at us. I managed to pick it up and throw it away before it exploded. So right after the war ended, a General gave me a sword, engraved with the words ‘Awarded for Bravery and Valor, A True Hero, World War 1’.”
The grandson thinks about the story for a minute and then says “Grandpa, that story can’t be true!” How did the grandson know?
It was the only World War at that time and World War 2 had not started yet. So, the sword should have been engraved with the words “World War” instead of “World War 1”.
It was called World War 1 only after World War 2 started.
