"Young Zaphod Plays It Safe" is a short story by Douglas Adams set in his The Hitchhiker's Guide to the Galaxy universe. It is included with several collections but has never been released as a standalone work. It first appeared in The Utterly Utterly Merry Comic Relief Christmas Book (1986) which Adams also co-edited. It also appears in slightly modified form in the Adams retrospective The Salmon of Doubt. The story also appears in some versions of the complete omnibus editions of The Hitchhiker's Guide to the Galaxy.
The story is a prequel to the events in The Hitchhiker's Guide to the Galaxy and has the young Zaphod Beeblebrox working as a salvage ship operator. He guides some bureaucrats to a crashed spaceship that may be leaking some dangerous materials, radioactive, toxic and otherwise hazardous by-products which were destined to be thrown into a black hole. The bureaucrats swear that it is "perfectly safe." When asked why they want to see it if that is true, they claim that they "like looking at things that are perfectly safe." The comic asides in the story include some of the time travel paradoxes which are a common running theme in Adams' SF work, and plenty of material about lobsters.
Since this was before Zaphod blocked off sections of his own brain for the presidency, readers are able to glimpse what his original personality was like. His general speech patterns and goof-off personality are the same, but he seems to have moral views and is more likely to go off on life-threatening and exciting quests for the greater good.
Throughout the story, it is emphasised that there is something particularly dangerous on board that ought to have been utterly destroyed, but is feared to have escaped.
Ultimately, it is revealed that the something was actually three identical "Designer People". The personalities seem totally benign, which is what makes them so dangerous. The ship is filled with substances so dangerous that they are safe because no one who would actually use them would be let near. The personalities, products of a Sirius Cybernetics Corporation project, however, have custom personalities that could not naturally exist. There is "nothing they will not do if allowed, and there is nothing they will not be allowed to do." Since no one will recognise that they are capable of mass destruction (despite their good intentions), no one will stop them from doing the unspeakable.
The story culminates with the revelation that one of the personalities has escaped and headed off into Galactic Sector ZZ9 Plural Z Alpha, which is where the Earth was located in the original Hitchhiker's Guide to the Galaxy.
Though it's not stated specifically, Adams implies that this unspeakably dangerous creation was then-President Ronald Reagan, a reflection of his critical views of the Reagan's policies which also surface in Mostly Harmless. A version of the story included in the posthumously-published The Salmon of Doubt makes this explicit.
