Watching hacker news try use cold analytical intellect to deconstruct 4chan's jokes and culture (and still missing the point) has got to be the funniest joke ever. Perhaps a little more analysis will yield the answer to understanding the complexity of a green frog or running bear. Though I wouldn't count on it. It has to mean something nefarious. Much like the soft 'schlop schlop schlop' of a dog's tongue lapping up water -- its meaning to us is a mystery.
From what I can tell, there's not much analysis of 4chan going on here, but more people just sort of remembering their time on the site.
That's what this has been for me; a walk down memory Lane to my teenage edgelord years.
