The folks at Rifftrax haven't riffed a civil defense short in a while. This ultra-low budget one was filmed in Austin, Texas for a local TV station. In spite of the grim subject matter, there's enough weirdness to riff over, like the extremely cramped fallout shelter in one family's home, the secretary who freaks out during the bombing (and turns into an extra from CARNIVAL OF SOULS), and (most especially) the idiot who disobeys all orders, and essentially winds up as compost.
