One of the major selling points of that wholly remarkable travel book, The Hitchhiker's Guide to the Galaxy, apart from its relative cheapness and the fact that it has the words DON'T PANIC written in large friendly letters on its cover, is its compendious and occasionally accurate glossary. The statistics relating to the geo-social nature of the Universe, for instance, are deftly set out between pages nine hundred and thirty-eight thousand three hundred and twenty-four and nine hundred and thirty-eight thousand three hundred and twenty-six; and the simplistic style in which they are written is partly explained by the fact that the editors, having to meet a publishing deadline, copied the information off the back of a packet of breakfast cereal, hastily embroidering it with a few footnotes in order to avoid prosecution under the incomprehensibly tortuous Galactic Copyright laws.
It is interesting to note that a later and wilier editor sent the book backward in time through a temporal warp, and then successfully sued the breakfast cereal company for infringement of the same laws.
Here is a sample:

The Universe--some information to help you live in it.

1 AREA: Infinite.

The Hitchhiker's Guide to the Galaxy offers this definition of the word "Infinite."
Infinite: Bigger than the biggest thing ever and then some. Much bigger than that in fact, really amazingly immense, a totally stunning size, real "wow, that's big," time. Infinity is just so big that, by comparison, bigness itself looks really titchy. Gigantic multiplied by colossal multiplied by staggeringly huge is the sort of concept we're trying to get across here.

2 IMPORTS: None.

It is impossible to import things into an infiinite area, there being no outside to import things in from.

3 EXPORTS: None.

See Imports.

4. POPULATION: None.

It is known that there are an infinite number of worlds, simply because there is an infinite amount of space for them to be in. However, not every one of them is inhabited. Therefore, there must be a finite number of inhabited worlds. Any finite number divided by infinity is as near to nothing as makes no odds, so the average population of all the planets in the Universe can be said to be zero. From this it follows that the population of the whole Universe is also zero, and that any people you may meet from time to time are merely the products of a deranged imagination.
