Finally, some proof.

Recently, I came across this article: Sarcasm Seen as Evolutionary Survival Skill.  "Tra la la!" I thought, "An article written for me, sort of about me!"

Here is an excerpt:
It's also easy to imagine how sarcasm might be selected over time as evolutionarily crucial. Imagine two ancient humans running across the savannah with a hungry lion in pursuit. One guy says to the other, "Are we having fun yet?" and the other just looks blank and stops to figure out what in the world his pal meant by that remark. End of friendship, end of one guy's contribution to the future of the human gene pool.

Fast forward a few million years and the network of human relationships is wider and more complex, and just as important to survival. The corporate chairman throws out a sarcastic remark and those who "get" it laugh, smile, and gain favor. In the same way, if the chair never makes a remark, sarcastic people are making them behind his or her back, forming a clique by their mutually negative, but funny, comments. Either way, sarcasm plays a role in making and breaking alliances and friendship.

Finally, someone understands.  If I'm reading this article correctly, and I am, it means that if you don't get my humor, you're not as evolved as I am.  And you haven't been properly socialized to comprehend complex human relationships and should be cast off from society and shunned until you cry so hard you dehydrate and die a painful death.

Laugh at my shit, people, it proves you're caught up with evolution.
