“Marvin started his ironical humming again. Zaphod hit him and he shut up.”

“Marvin was humming ironically because he hated humans so much.”

“If I ever meet myself,' said Zaphod, 'I'll hit myself so hard I won't know what's hit me.”

“Zaphod left the controls for Ford to figure out, and lurched over to Arthur."Look, Earthman," he said angrily, "you've got a job to do, right? The Question to the Ultimate Answer, right?""What, that thing?" said Arthur, "I thought we'd forgotten about that.""Not me, baby. Like the mice said, it's worth a lot of money in the right quarters. And it's all locked up in that head thing of yours.""Yes but ...""But nothing! Think about it. The Meaning of Life! We get our fingers on that we can hold every shrink in the Galaxy up to ransom, and that's worth a bundle. I owe mine a mint."Arthur took a deep breath without much enthusiasm."Alright," he said, "but where do we start? How should I know? They say the Ultimate Answer or whatever is Forty-two, how am I supposed to know what the question is? It could be anything. I mean, what's six times seven?"Zaphod looked at him hard for a moment. Then his eyes blazed with excitement."Forty-two!" he cried.Arthur wiped his palm across his forehead."Yes," he said patiently, "I know that."Zaphod's faces fell."I'm just saying that the question could be anything at all," said Arthur, "and I don't see how I am meant to know.”

“What's up?" [asked Ford.]"I don't know," said Marvin, "I've never been there.”

“Marvin trudged on down the corridor, still moaning. "...and then of course I've got this terrible pain in all the diodes down my left hand side...""No?" said Arthur grimly as he walked along beside him. "Really?""Oh yes," said Marvin, "I mean I've asked for them to be replaced but no one ever listens.""I can imagine.”

“His mouth started to speak, but his brain decided it hadn't got anything to say yet and shut it again. His brain then started to contend with the problem of what his eyes told it they were looking at, but in doing so relinquished control of the mouth which promptly fell open again. Once more gathering up the jaw, his brain lost control of his left hand which then wandered around in an aimless fashion. For a second or so the brain tried to catch the left hand without letting go of the mouth and simultaneously tried to think about what was buried in the ice, which is probably why the legs went and Arthur dropped restfully to the ground.”
