Robin - you can abbreviate 'Why, oh why' to YOY if you like. It's a new abbreviation popular on forums where people oft come to complain (see, for example, its widespread use on the Archers message board). If you are going to spell it out correctly, don't forget the comma.

I hadn't noticed COMrad. I have noticed, however, many BBC radio presenters saying 'tuh' instead of 'to' which vexes me greatly.
