Not the usual prison payback

As any inmate will tell you, when you're in prison, the one thing you have is time. That means that you have a lot of time to plan and fashion your way out, but some inmates at a federal prison decided instead to come up with a scheme usually reserved for corporations.

Four inmates filed to copyright their names, then demanded millions from the guard for using their names without permission. Let's just say it's not a good idea to mess with the warden.
