The Creo Manual Now on TV

I remember studying to re-sit exams so as to be able to go back to college after a less-that-glowing school career. I had to do physics and the text book seemed so...so....irreducibly complex. Stumbling across it 10 years later, I had to smile at the level of my ignorance then (save it Ringo )This video does raise a smile alright. Cheesy ain't the word. But there are simple-minded folk out there: both believers and non. You don't always need a hammer to crack a nut. If a banana suffices then fine.Folk can smile at their ignorance later on.

I think the expression was "poor in spirit". Its kind of an spiritual stupidity as opposed to an intellectual one.
