No idea why this was downvoted. I thought perhaps it's Rick Astley, but no. I found it quite instructive.

I found out about this channel a couple of days ago, and since then, I have watched a large chunk of the content. Rather than looking for something to kill time with on the boobtube, I've killed some time with this channel.
