YouTube commenters are well-known as being the 13 year old bottom-feeders of the internet. They and they alone make 4-Chan types look mature.
So when John Oliver decides to make a summer vacation web exclusive ON YOUTUBE reading YouTube comments to YouTube commenters, you know it's gonna be good.
As of this writing there are 2,993 comments on this YouTube video, the most prominent of which concern Pokemon Go.
Which I suspect to John Oliver? Makes absolute sense.
