What's in the First Episode?

The first episode was about how to find a celli. Do you get to choose your romain in prison? You don't want to go in there with somebody that you don't like. Can you deliver a berido from one floor to the next using the toilet? I was badyou can't just say that and not explain. A particular episode maybe that was most surprising to people who don't know anything about prisons, like me.
