'Mostly Harmless' by Douglas Adams

“The Hitch-Hiker’s Guide to the Galaxy has, in what we laughingly call the past, had a great deal to say on the subject of parallel universes. Very little of this is, however, at all comprehensible to anyone below the level of Advanced God, and since it is now well-established that all known gods came into existence a good three millionths of a second after the Universe began rather than, as they usually claimed, the previous week, they already have a great deal of explaining to do as it is, and are therefore not available for comment at this time…”

Mostly Harmless: The Hitch-Hiker’s Guide to the Galaxy Part Five. The book that gives a whole new meaning to the word ‘trilogy’.
