Also, the so-called lazy people are good for the economy, they're the ones who watch a lot of TV, get involved in many forms of entertainment, eat more food than they should. Giving them money just keeps them off the street. The non-lazy will be out and about or in their garage coming up with some human-made art - which I suspect will be of higher value than machine produced goods.

The support on this channel has been incredible and I now get more views and Likes on here than I do on my main glitching channel, so Thank You all so much for that. This is just a little video of an Easter Egg I found the day Shi No Numa was released. I'm filming a video for the Best Easter Eggs series but posted this just to stay active.
