Shortly before my father in law died, his wife told us he had worked on the Manhattan project. We had no idea, and when we asked him he said "That's classified". That was all he would say. We went home and laughed about it with my mom and step dad.
Several years later my step dad died. His brother told us he had worked on the Manhattan project! I could't believe that stinker laughed about my father in law with us, knowing he had the same secret!
That’s funny!
