No lor ... some people think wearing a burberry cap worn at a
jaunty angle = cool (when it is a scientific fact that it is most
uncool).
Also, it is not a simple matter of memorizing and practicing in
front of a mirror - most people will come out sounding like they
are chanting the scriptures...
Coaching on tone, appropriate pauses, grooming (like - just
guessing - maybe you should not wear shirts with very narrow
stripes - bloody annoying effect on screen), what to do with your
hands, etc.
