The favorite joke of Immanuel Kant:

The dignified funeral

A man arranges the funeral for his friend.
He wants to give him a dignified funeral.
But he will not succeed:
The more money he gives the pallbearers,
the happier they look.

Admittedly, this is no joke to bellow about. A quiet joke. The basic statement on which Kant was concerned is: "Dignity cannot be bought". 
Why do I like this joke? Because it illustrates a difficulty of emotional psychology: You can't order big feelings. It would be practical if you could use money from the test subjects to ensure that real joy, deep emotion, or even just ... Boredom can be created at will. Of course we try to achieve certain moods through music, pictures, sounds or films. But it will always be only a weak reflection of what we constantly experience in real life" for emotions. 

 

The favorite joke of Christian Kaernbach:

The business

The old Moische Goldberg, owner of a modest store, is dying.
The family has gathered around his deathbed.
Goldberg no longer sees well, and so he asks:
 "Rifke, my wife, are you there?" - "Yes, Moischele, I'm here."
 "Sarah, my daughter, are you there?" - "Yes, Tate, I'm here."
 "Jacob, my son, are you there?" - "Yes, Tate, I'm here."
And the old man straightens up with his last ounce of strength and screams angrily:
 "And who's in business?"

A joke with a surprising punch line that makes for a good laugh... ...only to be followed by some thought, even philosophy. If this joke were a wine, one would say about it: a sparkling drop with a cheerful flower - and a long, thought-provoking finish. That's the way wines are supposed to be. 

At first glance, Goldberg seems a fool: how can he worry about whether there is someone behind the counter of his small, insignificant store in the face of his approaching death? This extremely heightened sense of business, clichéd as typically Jewish, which seems completely out of place here, makes you laugh. But then you ask yourself: Does Goldberg know more? Does he know about the unimportance of his own existence? What does his death mean for the world? It will continue to turn. And his little store, is it really so insignificant? Life consists of giving and taking, of busy activity, of trade and change. Certainly his store is only a small cog in the wheel, but without these many small cog, without the many seemingly insignificant "stores", be they mercantile or of another nature, where would we be? Is not what we do more important than what we are? Goldberg would say: "Don't talk so much that your mouth gets fuzzy and your head starts spinning! Stand behind the counter again, there are more customers coming.

 

A Jewish joke by Christian Kaernbach:

The Messiah

Moische is truly a pious Jew. He lives entirely in the expectation of the Messiah.
He spends what he earns without saving, and does not worry about the future. 
When he is scolded for this, he replies, "Tomorrow the Messiah is coming! 
His acquaintances and friends have long since given up pointing this out to him, 
he said yesterday. His confession of faith comes so from the heart, 
that you cannot question it. 
One day the Messiah will come. Excitedly Moische runs towards him and calls to him:
"Master... ...didn't you want to come tomorrow?"

Is it permissible for a gentile to "invent" a Jewish joke just like that? Yes, one may, if one respects the spirit of the Jewish joke culture and is willing to apply the self-ironic tone of the Jewish joke to himself. And this joke is easy for a Christian to understand: Christians, too, expect the return of the Lord, and a pious Christian knows that he does not know the day or the hour, that the Lord can therefore also come tomorrow. Moische has made the best of his faith in the imminent return of the Lord: he lets things go well and does not save for the future. Obviously, he likes this life quite well, so it could go on like this. The Messiah, whose imminent arrival gives him the pretext for his carefree life, is only disturbing. This is of course contradictory in itself, and if the Messiah were humorless, he would be "not amused" by this reception. But Moische lives an unconditional yes to the now, and the Lord can only approve of that. After all, he has instructed us Christians: "Therefore do not worry about tomorrow, for tomorrow will take care of its own" (Mat 6:36). If the Messiah has a sense of humor - and this can be assumed - he will laugh, and Moische will ask if he has any money left over so that they can celebrate a little.
