Mostly Harmless

It's easy to become disheartened when your planet has been demolished for an unnecessary hyperspacial express route, the woman you love has vanished in a misunderstanding about the nature of space/time, the spaceship in which you are travelling crashed in flames on a remote and Bob-fearing planet, and all you have to fall back on are a few sandwich-making skills. However, instead of becoming disheartened, Arthur Dent makes the terrible mistake of starting to enjoy life a bit and immediately all hell breaks loose.
