Some great but rather random quotes from Douglas Adams:

"'So you see,' said Slartibartfast, slowly stirring his artificially constructed coffee, and thereby also stirring the whirlpool interfaces between real and unreal numbers, between the interactive perceptions of mind and universe, and thus generating the restructured matrices of implicitly enfolded subjectivity that alowed his ship to reshape the very concept of space and time, 'how it is.'"

"The second nonabsolute number [in a type of restaurant science known at bistromathics] is the given time of arrival, which is now known to be one of those most bizarre of mathematical concepts, a recipriversexcluson, a number whose existence can only be defined as being anything other than itself."

"There is an art to flying, or rather a knack. The knack lies in knowing how to throw yourself at the ground and miss."
