I almost thought the guy was right. The video is very convincing. However, an intelligent person would see the piece of pizza alone as a clue that the video is fake. Look at it.If it were really in the dirt, it would have had some dirt in it. And there isn't any dirt on it. Not only that, but conclusion #3 is the weirdest conclusion.

If the guy wanted people to figure out it's a joke, he did a good job. If he didn't want people to figure out it was a joke, he did a pretty bad job.
