I doubt if any pristine source material exists any more to make a good DVD. Still, the movie is a hoot, and gives more of a view of socialist thinking of the past (which hasn't changed to this very day), than a science fiction view of the future.
A thief burst into a Florida bank one day wearing a ski mask and carrying a gun. Aiming his gun at the guard, he thief yelled, "FREEZE, MOTHER-STICKERS, THIS IS A ****-UP!" For a moment, everyone was silent.
Then the snickers started. The guard completely lost it and doubled over laughing. It probably saved his life, because he'd been about to draw his gun. He couldn't have drawn and fired before the thief got him. The thief ran away and is still at large. In memory of the event, the banker later put a plaque on the wall engraved with the words, "Freeze, mother-stickers, this is a ****-up!"
