“The only thing nicer than a phone that didn't ring all the time (or indeed at all) was six phones that didn't ring all the time (or indeed at all).”

“The more Susan waited, the more the doorbell didn't ring. Or the phone.”

“How to Leave the Planet1. Phone NASA. Their phone number is (713) 483-3111. Explain that it’s very important that you get away as soon as possible.2. If they do not cooperate, phone any friend you may have in the White House—(202) 456-1414—to have a word on your behalf with the guys at NASA.3. If you don’t have any friends in the White House, phone the Kremlin (ask the overseas operator for 0107-095-295-9051). They don’t have any friends there either (at least, none to speak of), but they do seem to have a little influence, so you may as well try.4. If that also fails, phone the Pope for guidance. His telephone number is 011-39-6-6982, and I gather his switchboard is infallible.5. If all these attempts fail, flag down a passing flying saucer and explain that it’s vitally important that you get away before your phone bill arrives.”

“It is a rare mind indeed that can render the hitherto non-existent blindingly obvious. The cry 'I could have thought of that' is a very popular and misleading one, for the fact is that they didn't, and a very significant and revealing fact it is too.”

“during this century (the twentieth) we have for the first time been dominated by non-interactive forms of entertainment: cinema, radio, recorded music and television. Before they came along all entertainment was interactive: theatre, music, sport - the performers and audience were there together, and even a respectfully silent audience exerted a powerful shaping presence on the unfolding of whatever drama they were there for. We didn't need a special word for interactivity in the same way that we don't (yet) need a special word for people with only one head.I expect that history will show "normal" mainstream twentieth century media to be the aberration in all this. 'Please, miss, you mean they could only just sit there and watch? They couldn't do anything? Didn't everybody feel terribly isolated or alienated or ignored?'Yes, child, that's why they all went mad. Before the Restoration.'What was the Restoration again, please, miss?'The end of the twentieth century, child. When we started to get interactivity back.”

“Just supposing," he said, "just supposing" --he didn't know what was coming next, so he thought he'd just sit back and listen--"that there was some extraordinary way in which you were very important to me, and that, though you didn't know it, I was very important to you, but it all went for nothing because we only had five miles and I was a stupid idiot at knowing how to say something very important to someone I've only just met and not crash into lorries a the same time, what would you say..." He paused, helplessly, and looked at her."I should do.”

“You ARE Zaphod Beeblebrox?' 'Yeah,' said Zaphod, 'but don't shout it out or they'll all want one.' 'THE Zaphod Beeblebrox?' 'No, just A Zaphod Beeblebrox, didn't you hear I come in six packs?' 'But sir,' it squealed, 'I just heard on the sub-ether radio report. It said you were dead...' 'Yeah, that's right, I just haven't stopped moving yet.”
