"How can you tell?" asked Arthur. "Have you got some exotic device for measuring the age of metal?"
"No, I just found this sales brochure lying on the floor. It's a lot of `the Universe can be yours' stuff. Ah! Look, I was right."
Ford jabbed at one of the pages and showed it to Arthur.
"It says: Sensational new breakthrough in Improbability Physics. As soon as the ship's drive reaches Infinite Improbability it passes through every point in the Universe. Be the envy of other major governments. Wow, this is big league stuff."
Ford hunted excitedly through the technical specs of the ship, occasionally gasping with astonishment at what he read — clearly Galactic astrotechnology had moved ahead during the years of his exile.
Arthur listened for a short while, but being unable to understand the vast majority of what Ford was saying he began to let his mind wander, trailing his fingers along the edge of an incomprehensible computer bank, he reached out and pressed an invitingly large red button on a nearby panel. The panel lit up with the words Please do not press this button again. He shook himself.
"Listen," said Ford, who was still engrossed in the sales brochure, "they make a big thing of the ship's cybernetics. A new generation of Sirius Cybernetics Corporation robots and computers, with the new GPP feature."
"GPP feature?" said Arthur. "What's that?"
"Oh, it says Genuine People Personalities."
"Oh," said Arthur, "sounds ghastly."
