Best joke of all is 56 seconds in - at least with 2009 hindsight!
Those of us the wrong side of 40 are today being given an interesting glimpse into our own past with the release of the Government War Book, the official strategy manual for dealing with an escalation of hostilities during the Cold War. Throughout the era, Whitehall's finest would regularly carry out a full-scale theoretical exercise to test the contingency plans (replacing real Cabinet Ministers who were, to be honest, a bit rubbish at it).
Meanwhile, the Government's general information leaflet, optimistically entitled 'Protect And Survive', had a horrible fascination back in the 70's for those of us still living at home with our parents - the idea of being confined to the cupboard under the stairs for two weeks with the whole family coming pretty close to a teenager's definition of hell.
The general opinion, as far as I can remember, was that all this whitewashing and taping up of windows was an inspired ruse to keep us all out of the way while the Government and civil servants convened on their reinforced concrete bunkers. The rest of us lesser mortals would, of course, have to make do with a creative arrangement of doors and mattresses.
In our case, this would have been a fairly pointless exercise, given the nearby 'secret' submarine base - a prime target. In theory, we could have constructed a proper concrete shelter, but my father, on learning that the only local safe refuge was to house the Regional Council, announced that he had no intention whatsoever of surviving to emerge into a post-armageddon world populated by cockroaches and local politicians.
It's an interesting thought that the generation who fuelled the excesses of the 80's were subjected to all this at an impressionable age; eat, drink and be merry, for tomorrow we die!
