When we were implementing new kit at work last year my boss banned the word "Nightmare" because we were using it about so much of the project - it became "challenge". Mind you, we heard him say it too....

In the RN there is a course heading which you never put a ship on as it is the same number as the form used for reporting collisions/groundings etc. Can't remember what it is(which may prove a bit unfortunate...) - though I'm pretty sure Bert will know!
