There is nothing in which people more betray their character than in what they find to laugh at.

..to laugh is proper to the man.

Laughter is man's most distinctive emotional expression.

Some sleepers have intelligent faces even in sleep, while other faces, even intelligent ones, become very stupid in sleep and therefore ridiculous. I don't know what makes that happen; I only want to say that a laughing man, like a sleeping one, most often knows nothing about his face. A great many people don't know how to laugh at all. However, there's nothing to know here: it's a gift, and it can't be fabricated. It can only be fabricated by re-educating oneself, developing oneself for the better, and overcoming the bad instincts of one's character; then the laughter of such a person might quite possibly change for the better. A man can give himself away completely by his laughter, so that you suddenly learn all of his innermost secrets. Even indisputably intelligent laughter is sometimes repulsive. Laughter calls first of all for sincerity, and where does one find sincerity? Laughter calls for lack of spite, but people most often laugh spitefully. Sincere and unspiteful laughter is mirth. A man's mirth is a feature that gives away the whole man, from head to foot. Someone's character won't be cracked for a long time, then the man bursts out laughing somehow quite sincerely, and his whole character suddenly opens up as if on the flat of your hand. Only a man of the loftiest and happiest development knows how to be mirthful infectiously, that is, irresistibly and goodheartedly. I'm not speaking of his mental development, but of his character, of the whole man. And so, if you want to discern a man and know his soul, you must look, not at how he keeps silent, or how he speaks, or how he weeps, or even how he is stirred by the noblest ideas, but you had better look at him when he laughs. If a man has a good laugh, it means he's a good man. Note at the same time all the nuances: for instance, a man's laughter must in no case seem stupid to you, however merry and simplehearted it may be. The moment you notice the slightest trace of stupidity in someone's laughter, it un

He's the sort of guy that gets a laugh out of people.

If you wish to glimpse inside a human soul and get to know a man, don't bother analyzing his ways of being silent, of talking, of weeping, of seeing how much he is moved by noble ideas; you will get better results if you just watch him laugh. If he laughs well, he's a good man.

Men are funny characters, they must always have something to bemuse them.

A man never reveals his character more vividly than when portraying the character of another.

Only laughter makes a man rich, but the laughter has to be blissful.

There is nothing more precious than laughter

He who laughs at himself never runs out of things to laugh at.

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.

One cannot be always laughing at a man without now and then stumbling on something witty.

You can tell how smart people are by what they laugh at.
