Just when you think you know all the lingo of a particular industry - something else comes along to trick you.

I have just come from filming an interview for CRN TV - no, I'm not saying who it was.

I thought I had done quite a professional job, but when we were asked to 'do a couple of noddys' after the interview had ended I found it very hard to keep a straight face. Not very professional and apologies to my interviewee!

It almost spoils the moment by explaining what a 'noddy' is, if you haven't guessed already. It is basically nodding your head in response to a question - just so the film editors can get a different shot when a question is asked.

I will be prepared next time. But my interviewee stepped up to the mark in a very professional manner and produced a great noddy. No thanks to the grinning idiot opposite him.
