That was extremely strange. I thought you were showing off different parts of your body and how they could make sounds, but it was really just your mouth shown from different angles. I find "pie hole" to be one of the most insane names for a mouth ever. I thought it was just something that "Cow And Chicken" made up. I guess this succeeded in giving what it was supposed to. The lyrics aren't that bad if you listen to them.
For as nonsensical as this was, I didn't find it to be that creative. It was strange to see these black and white gifs of your mouth. I guess it could have been longer, but that probably wouldn't have made it make any more sense. I just wish it was more detailed. It's funny how a gray cartoon gate closes them.
