First let me drag something I said from another post, and all you have to do is exchange the word common sense for the word serious, then just have the word humor. Thank god my logic is able to morph, I hate typing
Common sense and a sense of humor are essentially the same thing, moving at different speeds. A sense of humor is just common sense moving at a superior speed, looking over its shoulder and laughing at common sense trying to catch up, but never will.
You see, I have a PHD in the arts. Surely it's not the same education as yours, but it works for me
PHD - Poor, Hungry, Driven Con artist does fall under the arts I hope
Now, let me explain a little about my world.
First, welcome to my world
Here you will be judged on what you wear, how you speak, which music you listen to, how you act, who you hang around with, and on every other personal trait and imperfection about you, and you'll be made fun of for who you are.
Enjoy your stay
Not that any of the above applies to you, this is humor being serious. How so? Most people are judgmental by nature, and the above is only the tip of the iceberg. So yes, that is pretty serious
What makes this humorous

Enjoy your stay does
Because I'm in a good mood and have 2 days off, I'll even toss in a bonus
Your quote - "Seriousness, by itself, implies the essence of tangability"
My counterpoint - Humor, in song
