“Yes it is,' said the Professor. 'Wait—' he motioned to Richard, who was about to go out again and investigate— 'let it be. It won't be long.'Richard stared in disbelief. 'You say there's a horse in your bathroom, and all you can do is stand there naming Beatles songs?'The Professor looked blankly at him.”
“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.”
“We already have the Wooden Pillar, the Steel Pillar and the Plastic Pillar. In a moment we will have the Golden Bail....'No, you won't.'We will,' stated the robot simply.No, you won't. It makes my ship work.'In a moment,' repeated the robot patiently, 'we will have the Golden Bail....'You will not,' said Zaphod.And then we must go,' said the robot, in all seriousness, 'to a party.'Oh,' said Zaphod, startled, 'can I come?'No,' said the robot, 'we are going to shoot you.'Oh, yeah?' said Zaphod, waggling his gun.Yes,' said the robot, and they shot him.Zaphod was so surprised that they had to shoot him again before he fell down. (85-86)”
“I think he probably wants you to play Scrabble with him again,' said Ford, 'he's pointing to the letters.''Probably spelt crzjgrdwldiwdc again, I keep on telling him there's only one g in crzjgrdwldiwdc.”
“But that can't work, can it?" Said Richard. "If we do that, then this won't have happened. Don't we generate all sorts of paradoxes?"Reg stirred himself from thought. "No worse than many that exist already," he said. "If the universe came to an end every time there was some uncertainty about what had happened in it, it would never have got beyond the first picosecond. And many of course don't. It's like a human body, you see. A few cuts and bruises here and there don't hurt it. Not even major surgery if its done properly. Paradoxes are just the scar tissue. Time and space heal themselves up around them and people simply remember a version of events which makes as much sense as they require it to make. That isn't to say if you get involved in a paradox a few things won't strike you as being very odd, but if you've got through life without that already happening to you, then I don't know which universe you've been living in, but it isn't this one”
“No," he said, "look, it's very, very simple ... all I want ... is a cup of tea. You are going to make one for me. Keep quiet and listen." And he sat. He told the Nutri-Matic about India, he told it about China, he told it about Ceylon. He told it about broad leaves drying in the sun. He told it about silver teapots. He told it about summer afternoons on the lawn. He told it about putting in the milk before the tea so it wouldn't get scalded. He even told it (briefly) about the history of the East India Company."So that's it, is it?" said the Nutri-Matic when he had finished. "Yes," said Arthur, "that is what I want.""You want the taste of dried leaves in boiled water?""Er, yes. With milk.""Squirted out of a cow?""Well, in a manner of speaking I suppose ...”
“O Deep Thought computer," he said, "the task we have designed you to perform is this. We want you to tell us...." he paused, "The Answer.""The Answer?" said Deep Thought. "The Answer to what?""Life!" urged Fook."The Universe!" said Lunkwill."Everything!" they said in chorus.Deep Thought paused for a moment's reflection."Tricky," he said finally."But can you do it?"Again, a significant pause."Yes," said Deep Thought, "I can do it.""There is an answer?" said Fook with breathless excitement."Yes," said Deep Thought. "Life, the Universe, and Everything. There is an answer. But, I'll have to think about it."...Fook glanced impatiently at his watch.“How long?” he said.“Seven and a half million years,” said Deep Thought.Lunkwill and Fook blinked at each other.“Seven and a half million years...!” they cried in chorus.“Yes,” declaimed Deep Thought, “I said I’d have to think about it, didn’t I?"[Seven and a half million years later.... Fook and Lunkwill are long gone, but their descendents continue what they started]"We are the ones who will hear," said Phouchg, "the answer to the great question of Life....!""The Universe...!" said Loonquawl."And Everything...!""Shhh," said Loonquawl with a slight gesture. "I think Deep Thought is preparing to speak!"There was a moment's expectant pause while panels slowly came to life on the front of the console. Lights flashed on and off experimentally and settled down into a businesslike pattern. A soft low hum came from the communication channel."Good Morning," said Deep Thought at last."Er..good morning, O Deep Thought" said Loonquawl nervously, "do you have...er, that is...""An Answer for you?" interrupted Deep Thought majestically. "Yes, I have."The two men shivered with expectancy. Their waiting had not been in vain."There really is one?" breathed Phouchg."There really is one," confirmed Deep Thought."To Everything? To the great Question of Life, the Universe and everything?""Yes."Both of the men had been trained for this moment, their lives had been a preparation for it, they had been selected at birth as those who would witness the answer, but even so they found themselves gasping and squirming like excited children."And you're ready to give it to us?" urged Loonsuawl."I am.""Now?""Now," said Deep Thought.They both licked their dry lips."Though I don't think," added Deep Thought. "that you're going to like it.""Doesn't matter!" said Phouchg. "We must know it! Now!""Now?" inquired Deep Thought."Yes! Now...""All right," said the computer, and settled into silence again. The two men fidgeted. The tension was unbearable."You're really not going to like it," observed Deep Thought."Tell us!""All right," said Deep Thought. "The Answer to the Great Question...""Yes..!""Of Life, the Universe and Everything..." said Deep Thought."Yes...!""Is..." said Deep Thought, and paused."Yes...!""Is...""Yes...!!!...?""Forty-two," said Deep Thought, with infinite majesty and calm.”
