Absolutely priceless!! I can't say that I have been in that "tight" a situation yet while teaching but as I tell people all the time, teaching is one part planning and two parts improve. Things go wrong all the time and if you can't adjust your plan or roll with the punches then you are going to be pulling your hair out from the roots. Great job finding a way to "think" outside the box you just happened to be trapped in. Too funny! Thanks for sharing, I know I am laughing.
