The Perfect Golf Swing!

I ran across this ad in my inbox and it started me thing.  First thought is you would be wasting your money to buy this and the second thing is what exactly makes up a "Perfect Golf Swing"? 

I hear that term used a lot - particularly in marketing of golf products, but I've never seen a definition of it.

I would love to hear your thoughts on the subject.  Please leave comments with your thoughts.
