“Having solved all the major mathematical, physical, chemical, biological, sociological, philosophical, etymological, meteorological and psychological problems of the Universe except for his own, three times over, [Marvin] was severely stuck for something to do, and had taken up composing short dolorous ditties of no tone, or indeed tune. The latest one was a lullaby.Marvin droned,Now the world has gone to bed,Darkness won't engulf my head,I can see in infrared,How I hate the night.He paused to gather the artistic and emotional strength to tackle the next verse.Now I lay me down to sleep,Try to count electric sheep,Sweet dream wishes you can keep,How I hate the night.”

“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.”

“It's the story of my life. You see, the quality of any advice anybody has to offer has to be judged against the quality of life they actually lead. Now, as you look through this document you'll see that I've underlined all the major decisions I ever made to make the stand out. They're all indexed and cross-referenced. See? All I can suggest is that if you take decisions that are exactly opposite to the sort of decisions that I've taken, then maybe you won't finish up at the end of your life" --she paused, and filled her lungs for a good should--"in a smelly old cave like this!”

“It is a mistake to think you can solve any major problems just with potatoes.”

“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.”

“It's part of the shape of the Universe. I only have to talk to somebody and they begin to hate me.”

“I'm up to here with cool, okay? I am so amazingly cool you could keep a side of meat in me for a month. I am so hip I have difficulty seeing over my pelvis.”
