I remember watching a news item a few years ago where they were interviewing Inspector Knacker of The Yard over some incident, over his shoulder in the background you could see a terminal on a desk and written above it on the whiteboard in HUGE letters was :
Username: PCPlod
Password: hefelldownthestairsyourhonour
(names changed to protect the guilty)
Anyway in the interests of reporting accuracy I tried to track down the actual incident and googled "police password written on whiteboard" and there's fscking dozens of them !!!!!!
