There's a concept that I tend to think of as "Haha, only so serious" for lacking a better way to describe it.
I tend to view seriousness and humor as a balanced dualism that goes hand in hand rather than as diametrically opposed sides of the coin. The best humor tends to filter through by taking ourselves seriously, but not oh so seriously that we forget to laugh in the moment.
Perhaps I feel this way because life tends to be more like The Joker's laugh after Batman wins and pawns him off on commissioner Gordan. Far more than our laughter in the real world tends to be as brazen as a chorus doing the can-can. Thus as someone who enjoys a good laugh, I tend to appreciate humor that stems from not taking oneself too seriously.
