I have this scene in my head where Gen. Kelly is unpacking his things into the CoS office, an assistant pops in and asks if he needs anything. He says it'd be great if you could print off a copy of the flow-chart so he can get an idea of the chain of command around here. Assistant stares blankly back at him for a second and then starts laughing.
ETA: Assistant walks over to whiteboard, writes "PRESIDENT" with a circle around it, then proceeds to list all other positions with a line linking back to this. "There's your flow-chart, there's some dashed-line connections, too, but they change every few hours or so. Good luck!"
