Lol you continue to troll, okay man. I find it fascinating you think there has to be a grand reason behind the posting of a youtube link.
Also pretty sure I did answer, but hey maybe I forgot to so I will just post what I think I already posted: the answer to your question mostly comes down to: because I can lol. Cuz this is a thread where people post this kinda thing, and because I know some others here enjoy Andy's videos.
That's it, that is the answer to the mystery you've apparently been seeking. I suppose in a way I understand, online when someone types something you obviously don't hear their tone when they say it. But yeah, I'm off to smoke a bowl and watch me a Henry Mudd episode of Trek.
