We demand rigidly defined areas of doubt and uncertainty! - Douglas Adams, The Hitchhiker's Guide to the Galaxy

"Space is big. You just won't believe how vastly, hugely, mind-bogglingly big it is. I mean, you may think it's a long way down the road to the chemist's, but that's just peanuts to space."

"What does it matter? Science has achieved some wonderful things, of course, but I'd far rather be happy than right any day."

"Arthur blinked at the screens and felt he was missing something important. Suddenly he realized what it was."Is there any tea on this spaceship?"he asked."

"So this is it,"said Arthur, "We are going to die.""Yes,"said Ford, "except... no! Wait a minute!"He suddenly lunged across the chamber at something behind Arthur's line of vision. "What's this switch?"he cried."What? Where?"cried Arthur, twisting round."No, I was only fooling,"said Ford, "we are going to die after all."

"I think you ought to know I'm feeling very depressed."
