I found a very strange video on YouTube that I feel should absolutely be mentioned. It appears to be a video made from GMod clips, featuring all sorts of cameos. The format of this video reminds me of Robot Chicken, only it makes a lot less sense and is much more random.
This video isn’t really funny on merit. Instead, I found myself laughing a few times just over how bizarre and random the video is.
So here it is, Half Retarded II: Episode I.
