Arthur blinked at the screens and felt he was missing something important. Suddenly he realized what it was. "Is there any tea on this spaceship?" he asked.

Simple. I got very bored and depressed, so I went and plugged myself in to its external computer feed. I talked to the computer at great length and explained my view of the Universe to it," said Marvin. "And what happened?" pressed Ford. "It committed suicide," said Marvin and stalked off back to the Heart of Gold.

Bistromathics itself is simply a revolutionary new way of understanding the behavior of numbers. Just as Einstein observed that space was not an absolute but depended on the observer's movement in space, and that time was not an absolute, but depended on the observer's movement in time, so it is now realized that numbers are not absolute, but depend on the observer's movement in restaurants.

Well, I mean, yes idealism, yes the dignity of pure research, yes the pursuit of truth in all its forms, but there comes a point I'm afraid where you begin to suspect that the entire multidimensional infinity of the Universe is almost certainly being run by a bunch of maniacs. And if it comes to a choice between spending yet another ten million years finding that out, and on the other hand just taking the money and running, then I for one could do with the exercise.

The waiter approached. 'Would you like to see the menu?' he said. 'Or would you like to meet the Dish of the Day?' 'Huh?' said Ford. 'Huh?' said Arthur. 'Huh?' said Trillian. 'That’s cool,' said Zaphod. 'We'll meet the meat.

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.
