From The Restaurant at the End of the Universe:
Number Two's eyes narrowed and became what are known in the Shouting and Killing People trade as cold slits, the idea presumably being to give your opponent the impression that you have lost your glasses or are having difficulty keeping awake. Why this is frightening is an, as yet, unresolved problem.
He advanced on the Captain, his (Number Two's) mouth a thin hard line. Again, tricky to know why this is understood as fighting behavior.
Trouble with a long journey like this,continued the Captain,is that you end up just talking to yourself a lot, which gets terribly boring because half the time you know what you're going to say next.
Only half the time?asked Arthur in surprise.The Captain thought for a moment.
Yes, about half, I'd say....
Crash?shouted Ford and Arthur.
Er, yes,said the Captain,yes, it's all part of the plan, I think. There was a terribly good reason for it which I can't quite remember at the moment. It was something to do with...er...Ford exploded.
You're a load of useless bloody loonies!he shouted.
Ah yes, that was it,beamed the Captain,that was the reason.
Things not to do with scrabble letters.
He picked up the letter Q and hurled it into a distant privet bush where it hit a young rabbit. The rabbit hurtled off in terror and didn't stop till it was set upon and eaten by a fox which choked on one of its bones and died on the bank of a stream which subsequently washed it away.
During the following weeks Ford Prefect swallowed his pride and struck up a relationship with a girl who had been a personnel officer on Golgafrincham, and he was terribly upset when she suddently passed away as a result of drinking water from a pool that had been polluted by the body of a dead fox. The only moral it is possible to draw from this story is that one should never through the letter Q into a privet bush, but unfortunately there are times when it is unavoidable.
I hope you've enjoyed these excerpts. I encourage you to read Douglas Adams' books, as they are fabulously funny, yet not entirely devoid of deep meaning.
