"Life is wasted on the living."

"He stood up straight and looked the world squarely in the fields and hills. To add weight to his words he stuck the rabbit bone in his hair. He spread his arm out wide. "I will go mad!" he annouced."

"Exactly!" said Deep Thought. "So once you do know what the question actually is, you'll know what the answer means."

"Life... is like a grapefruit. Well, it's sort of orangey-yellow and dimpled on the outside, wet and squidgy in the middle. It's got pips inside, too. Oh, and some people have half a one for breakfast."

"We demand rigidly defined areas of doubt and uncertainty!"

"All opinions are not equal. Some are a very great deal more robust, sophisticated and well supported in logic and argument than others."

"We are stuck with technology when what we really want is just stuff that works."

"This must be Thursday,' said Arthur to himself, sinking low over his beer. 'I never could get the hang of Thursdays."

"A learning experience is one of those things that says, 'You know that thing you just did? Don't do that."

"I may not have gone where I intended to go, but I think I have ended up where I needed to be."

"There's always a moment when you start to fall out of love, whether it's with a person or an idea or a cause, even if it's one you only narrate to yourself years after the event: a tiny thing, a wrong word, a false note, which means that things can never be quite the same again."

"The Hitch Hiker's Guide to the Galaxy offers this definition ofthe word "Infinite".Infinite: Bigger than the biggest thing ever and then some.Much bigger than that in fact, really amazingly immense, atotally stunning size, "wow, that's big", time. Infinity is just sobig that by comparison, bigness itself looks really titchy.Gigantic multiplied by colossal multiplied by staggeringlyhuge is the sort of concept we're trying to get across here."

"My capacity for happiness," he added, "you could fit into a matchbox without taking out the matches first"

"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,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,"

"The first ten million years were the worst," said Marvin, "and the second ten million years, they were the worst too. The third ten million years I didn't enjoy at all. After that I went into a bit of a decline."

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

"Shee, you guys are so unhip it's a wonder your bums don't fall off."

"Why?' is always the most difficult question to answer. You know where you are when someone asks you 'What's the time?' or 'When was the battle of 1066?' or 'How do these seatbelts work that go tight when you slam the brakes on, Daddy?' The answers are easy and are, respectively, 'Seven-thirty in the evening,' 'Ten-fifteen in the morning,' and 'Don't ask stupid questions."

"Ford carried on counting quietly. This is about the most aggressive thing you can do to a computer, the equivalent of going up to a human being and saying "Blood...blood...blood...blood..."

"Ow! My brains!"

"I have detected disturbances in the wash.''The wash?''The space-time wash.''Are we talking about some sort of Vogon laundromat, or what are we talking about?''Eddies in the space-time continuum.''Ah...is he. Is he.''What?''Er, who is Eddy, then, exactly?"

"I think fish is nice, but then I think that rain is wet, so who am I to judge?"
