@manored,
There was once a man seeking the meaning of life, who quit his job, left his family and traveled across the wide ocean, through jungles, over deserts, and over mountains to find the wisest man in the world; and when he found this man he said: oh wise man; tell me what is life???
And the wise man said: My son; Life is a fountain....
The seeker nodded thoughtfully for a moment to consider the wisdom...
Then he said: Do you mean to tell me that I quit my job, and left my family and traveled over ocean, jungle, deserts and mountains to have you tell me some nonsense like: life is a fountain???...
Okay; said the wise one... So, it's not a fountain...
That is not just my best philosophical joke; it is by only joke about philosophy I know...Of course, one may consider the philosophy of humor generally...
