Congrats mattrom and thanks buddy.
I wouldn't have liked to be lectured by that guy - I couldn't hear much that he was saying!
(When I was a chemistry student at Cambridge, I was looking forward to lectures on organic chemistry by Peter Sykes, who had written a great book on organic mechanisms. He was dreadful. He recognised that many students wouldn't bother to go to his lectures, but he lost grip on reality and recorded them on cassette tape, putting the tapes in the library for students to "listen to them later" (as if!). The last straw for me was when he had been talking for about forty minutes he looked down and said "I've forgotten to start the recorder". He started it, then went back to the beginning of the lecture and repeated the first forty minutes!)
