Here's a trip down Nostalgia Lane for those of you in your later 50s or older. It's one of the famous "Duck and Cover" films, produced by the Civilian Defense Administration in the early 1950s and aimed at teaching you how to survive a nuclear attack. Of course, we know now that is laughably preposterous. They'd have done a much better public service by producing a "Gumby" video, teaching everyone how to be flexible enough to "kiss your ass good-bye."
And, for those of you 45 and younger: maybe this film help explain why at least some of your elders are screwed up.
