Vieil océan, tu es le symbole de l'identité: toujours égal à toi-même. Tu ne varies pas d'une manière essentielle, et, si tes vagues sont quelque part en furie, plus loin, dans quelque autre zone, elles sont dans le calme le plus complet. Tu n'es pas comme l'homme, qui s'arrête dans la rue, pour voir deux boule-dogues s'empoigner au cou, mais, qui ne s'arrête pas, quand un enterrement passe; qui est ce matin accessible et ce soir de mauvaise humeur; qui rit aujourd'hui et pleure demain. Je te salue, vieil océan!

“He had the same sombre expression and heavy foot that they all have — and the same lack of humour.”
Original short-story, "The Stainless Steel Rat" in Astounding magazine (August 1957) http://www.iol.ie/~carrollm/hh/ssrshort.htm
The Stainless Steel Rat
Context: When the office door opened suddenly I knew the game was up. It had been a money-maker — but it was all over. As the cop walked in I sat back in the chair and put on a happy grin. He had the same sombre expression and heavy foot that they all have — and the same lack of humour. I almost knew to the word what he was going to say before he uttered a syllable.
"James Bolivar diGriz I arrest you on the charge—"
I was waiting for the word charge, I thought it made a nice touch that way. As he said it I pressed the button that set off the charge of black powder in the ceiling, the crossbeam buckled and the three-ton safe dropped through right on the top of the cop's head. He squashed very nicely, thank you. The cloud of plaster dust settled and all I could see of him was one hand, slightly crumpled. It twitched a bit and the index finger pointed at me accusingly. His voice was a little muffled by the safe and sounded a bit annoyed. In fact he repeated himself a bit.
"On the charge of illegal entry, theft, forgery—"
He ran on like that for quite a while, it was an impressive list but I had heard it all before. I didn't let it interfere with my stuffing all the money from the desk drawers into my suitcase. The list ended with a new charge and I would swear on a stack of thousand credit notes that high that there was a hurt tone in his voice.
"In addition the charge of assaulting a police robot will be added to your record."

Inspector Singh Investigates: A Most Peculiar Malaysian Murder, Cap 19
Context: But these quiet people, in their animal skin clothes with their diet of sago, were not to be left alone to wander through the lush jungles, living off the land, leaving no mark when they moved on, teaching their children the secrets of the forest. The greed of others could not co-exist with the selflessness of the Penan with their gentle humour and generous hearts.

"Einstein's Reply to Criticisms" (1949), The World As I See It (1949)
Context: There are few enough people with sufficient independence to see the weaknesses and follies of their contemporaries and remain themselves untouched by them. And these isolated few usually soon lose their zeal for putting things to rights when they have come face to face with human obduracy. Only to a tiny minority is it given to fascinate their generation by subtle humour and grace and to hold the mirror up to it by the impersonal agency of art. To-day I salute with sincere emotion the supreme master of this method, who has delighted — and educated — us all.

63 : The Working of the Avatar, p. 105.
The Everything and the Nothing (1963)
Context: The Avatar draws upon Himself the universal suffering, but He is sustained under the stupendous burden by His Infinite Bliss and His infinite sense of humour. The Avatar is the Axis or Pivot of the universe, the Pin of the grinding-stones of evolution, and so has a responsibility towards everyone and everything.

“Lateral thinking is closely related to insight, creativity and humour.”
Source: Lateral Thinking : Creativity Step by Step (1970), p. 6; First paragraph of the introduction.
Context: Lateral thinking is closely related to insight, creativity and humour. All four processes have the same basis. But whereas insight, creativity and humour can only be prayed for, lateral thinking is a more deliberate process. It is as definite a way of using the mind as logical thinking — but a very different way.
Ham and Tongue.
One-Half of Robertson Davies (1977)
Context: I have never consciously "used" humour in my life. Such humour as I may have is one of the elements in which I live. I cannot recall a time when I was not conscious of the deep, heaving, rolling ocean of hilarity that lies so very near the surface of life in most of its aspects. If I am a moralist — and I suppose I am — I am certainly not a gloomy moralist, and if humour finds its way into my work it is because I cannot help it.
