“And so the Universe ended.” 

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

“One of the things Ford Prefect had always found hardest to understand about human beings was their habit of continually stating and repeating the very very obvious, as in It's a nice day, or You're very tall, or Oh dear you seem to have fallen down a thirty-foot well, are you all right? At first Ford had formed a theory to account for this strange behaviour. If human beings don't keep exercising their lips, he thought, their mouths probably seize up. After a few months' consideration and observation he abandoned this theory in favour of a new one. If they don't keep on exercising their lips, he thought, their brains start working.”

“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.” 

“Life is wasted on the living.” 

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

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

In order to fly, all one must do is simply miss the ground.
