A little book quote of my own:
Zaphod sighed a “what is the world coming to” sort of sigh to absolve himself from all blame, and swung himself round in his seat.
“Ship?” he called.
“Yup?” said the ship.
“Do what I do.”
The ship thought about this for a few milliseconds and then, after double checking all the seals on its heavy duty bulkheads, it began slowly, inexorably, in the hazy blaze of its lights, to sink to the lowest depths.
