"Laughter, on the other hand, " Petrarch went on, "is an explosion that tears us away from the world and throws us back into our own cold solitude. Joking is a barrier between man and the world. Joking is the enemy of love and poetry. That's why I tell you yet again, and you want to keep in mind: Boccaccio doesn't understand love. Love can never be laughable. Love has nothing in common with laughter."

A joke is an epigram on the death of a feeling.

Jokiness allows a constant trivializing: as if by joking someone is suspending judgment on what is being said. She didn’t mean anything by it; lighten up. A killjoy knows from experience: when people keep making light of something, something heavy is going on

A joke is a very serious thing.

The telling of jokes is an art of its own, and it always rises from some emotional threat. The best jokes are dangerous, and dangerous because they are in some way truthful.

It does seem to me that the job of comedy is to offend, or have the potential to offend, and it cannot be drained of that potential. Every joke has a victim. That’s the definition of a joke. Someone or something or an idea is made to look ridiculous....In a proper free society, you should be allowed to make jokes about absolutely anything.

To joke in the face of danger is the supreme politeness, a delicate refusal to cast oneself as a tragic hero; panache is therefore a timid heroism, like the smile with which one excuses one's superiority.

A joke's a very serious thing.

And what exactly is a dream, and what exactly is a joke?

The specific element that occurs in every single successful joke is surprise. Surprise. A line of logic is going one way, and then, it doesn't. I call it "making non-sense". You go "That doesn't make any sense, but I get it." That-- That's the words that people use to describe a joke: "I got it."

Jokes [are] the bane of every trasnlator's existence.

A joke is like building a mousetrap from scratch. You have to work pretty hard to make the thing snap when it is supposed to snap.

So when all the yielding and objections is over, the other Senator said, "I object to the remarks of a professional joker being put into the Congressional Record." Taking a dig at me, see? They didn't want any outside fellow contributing. Well, he had me wrong. Compared to them I'm an amateur, and the thing about my jokes is that they don't hurt anybody. You can say they're not funny or they're terrible or they're good or whatever it is, but they don't do no harm. But with Congress — every time they make a joke it's a law. And every time they make a law it's a joke.

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?
