  1. Interesting video, but why the hell have Charlie McDonnell and the other idiot on there? "Celebrity" factor, or merely just to give them more publicity for doing f*ck all?

    • No they are just friends hanging out doing things they like togehter: making youtube videos. As a youtuber you don't have co-workers as if you were employed at a company so you interact with other youtube makers and you become some sort of colleagues and make video collaborations. Cheer up! It's not like the video lose quality.
