Tom Marsh. This guy was great. No boring lectures from him - ever. Every 10th word or so during his lectures, he would practically SCREAM whatever it was he was saying, and then immediatly drop back down to normal speaking tone. It didn't matter what he was talking about - you were forced to listen, because he was so entertaining. Truly the mark of a great teacher. If they won't listen, act like a absolute NUT until they are fixated on your every word.
