I read "Ghost in the Wires" (a book about Kevin Mitnick's life) a month or two ago, and it's astonishing how well he knew the system. He was doing stuff like the above, but also getting around the callback as well (I don't recall exactly what he did, but it was something along the lines of conning the line workers to divert an exec's phone number for testing purposes just long enough to get the callback). That was just one of many times he pulled these sorts of stunts for curiousity's sake.
