Porta John Falls Over With Guy Inside, AFV, Video. This is sooo nasty. I have worked at a construction site. This is super nasty. It is all over the guy. On a brighter note, notice the guy is wearing a suit and tie. That means he is not from the construction site. That means the construction crew has something to laugh about every day they go to work They just have to remember the time that guy came to the site and got trapped in the Porta John.
