Ring-a-ding dong, I can write stupid songs, now where's my money - wait! Just put it in mah thong.

— Possible mottos for humanity —

"Humanity:

Don't know, don't care;
Don't care that we don't know, don't want anyone to know that we don't care;
Been everywhere, done everything - learned absolutely fuckin' nothing;
A life full of stuff just might fill the void where intellect should have been, somehow;
Reality is just a theory and shouldn't be taught anywhere;
We're basically potatoes, give or take a few millivolts;
Literally dumber than the simplest machines we make;"

And, last but—in my humble opinion—best...

"Humanity: Because it takes more energy to let ourselves die than to allow our momentum to perpetuate this awful, truly upsetting existence - and we're so lazy we can't even give a single fuck anymore, even about ourselves."

Yeah! That's the one. It's got a nice, truthful ring to it.
