Not sure. Those who tell the story seem to emphasize the serious nature of the comment. Perhaps there was some nervous laughter. Anyone here who was at least a teenager at the time might be able to comment on whether the gravity of the situation had really sunk in less than a day. I was six and had no idea who (or even what) the President was. My world was my parents, my teacher, my classmates, a few friends on the street where I lived, their parents, and maybe a handful of cartoon characters. I only remember my parents sitting very close to the TV, which they never did (only my sister and I did that). This about sums it all up - Opinion | He Played Kennedy. Then He Became Himself. Since this thread relates to lost TV shows, I'll note there seem to be extremely few lost What's My Line episodes (no more than five since I started watching circa 1955). They have been remarkably well preserved.
