There's only one joke worth laughing at and it's the joke of existence.

George, you must realize that the world is a joke. There is no justice, everything is random. Only when you realize this will you understand how silly it is to take yourself seriously. There is no grand purpose in the universe. It just is. There’s no particular meaning in what decision you make today about how to act.

If you can't joke about the most horrendous things in the world, what's the point of jokes? What's the point in having humor? Humor is to get us over terrible things.

The world is indeed comic, but the joke is on mankind.

Some jokes are less agreeable than others

There are certain queer times and occasions in this strange mixed affair we call life when a man takes this whole universe for a vast practical joke, though the wit thereof he but dimly discerns, and more than suspects that the joke is at nobody's expense but his own.

…she did not believe that the world was a vale of tears but rather a joke that God had played and that it was idiotic to take it seriously if He himself never had.

It is the test of a good religion whether you can joke about it.

A serious and good philosophical work could be written consisting entirely of jokes.

It's all a joke! Everything anybody ever valued or struggled for... it's all a monstrous, demented gag! So why can't you see the funny side? Why aren't you laughing?

A good laugh is a mighty good thing, and rather too scarce a good thing; the more's the pity. So, if any one man, in his own proper person, afford stuff for a good joke to anybody, let him not be backward, but let him cheerfully allow himself to spend and be spent in that way. And the man that has anything bountifully laughable about him, be sure there is more in that man than you perhaps think for.

Practical jokes are a demonstration that the distinction between seriousness and play is not a law of nature but a social convention which can be broken, and that a man does not always require a serious motive for deceiving another.

Two men, dressed as city employees, block off a busy street and start digging it up. The traffic cop, motorists and pedestrians assume that this familiar scene has a practical explanation – a water main or an electric cable is being repaired – and make no attempt to use the street. In fact, however, the two diggers are private citizens in disguise who have no business there.

All practical jokes are anti-social acts, but this does not necessarily mean that all practical jokes are immoral. A moral practical joke exposes some flaw of society which is hindrance to a real community or brotherhood. That it should be possible for two private individuals to dig up a street without being stopped is a just criticism of the impersonal life of a large city where most people are strangers to each other, not brothers; in a village where all inhabitants know each other personally, the deception would be impossible.

There is no situation in life but has its advantages and pleasures — provided we will but take a joke as we find it

It is — or seems to be — a wise sort of thing, to realise that all that happens to a man in this life is only by way of joke, especially his misfortunes, if he have them. And it is also worth bearing in mind, that the joke is passed round pretty liberally & impartially, so that not very many are entitled to fancy that they in particular are getting the worst of it.
