From The Great Escape
Dennis, maps and surveys. Colin, you'll take your usual job. Eric, have you thought how you're going to get rid of this dirt?
Yes, I have. The usual places. I hadn't anticipated three tunnels, but we'll manage.
Roger, who's going to handle security for all this?
You are. I want a system of stooges covering this compound from front to back, checking every goon in and out. I want a signal system so perfect that if ever a ferret gets within fifty feet of any of the huts in which we're working, we can shut down without a sign.
