Yeh this is funny  :  )  What is it from?

Ideas: I don't think sane people gathering together is anything 'new', but that it's been going on for thousands of years.
...And I think for a clearer pov I'd reverse the percentages -IRL most of the world is 'the underground'; society is a tiny island on the surface of this planet, even though it would like people to believe otherwise. We shouldn't forget that -every day we are surrounded by thousands of species thriving -why not join in? LOL  :  )
Best,
