“Come on,” he droned, “I’ve been ordered to take you down to the bridge. Here I am, brain the size of a planet and they ask me to take you down to the bridge. Call that job satisfaction? ’Cos I don’t.”He turned and walked back to the hated door.“Er, excuse me,” said Ford following after him, “which government owns this ship?”Marvin ignored him.“You watch this door,” he muttered, “it’s about to open again. I can tell by the intolerable air of smugness it suddenly generates.”

“Ghastly," continued Marvin, "it all is. Absolutely ghastly. Just don't even talk about it. Look at this door," he said, stepping through it. The irony circuits cut in to his voice modulator as he mimicked the style of the sales brochure. " 'All the doors in his spaceship have a cheerful and sunny disposition.

“Sir Isaac Newton, renowned inventor of the milled-edge coin and the catflap!""The what?" said Richard."The catflap! A device of the utmost cunning, perspicuity and invention. It is a door within a door, you see, a ...""Yes," said Richard, "there was also the small matter of gravity.""Gravity," said Dirk with a slightly dismissed shrug, "yes, there was that as well, I suppose. Though that, of course, was merely a discovery. It was there to be discovered." ... "You see?" he said dropping his cigarette butt, "They even keep it on at weekends. Someone was bound to notice sooner or later. But the catflap ... ah, there is a very different matter. Invention, pure creative invention. It is a door within a door, you see.”

“The door was the way to... to... The Door was The Way. Good. Capital letters were always the best way of dealing with things you didn't have a good answer to.”
