The statistic that I hated to hear was that speakers make an impact almost entirely through physical style rather than content. Sure, a speech without content is still a usually failure (unless your audience is, oh, the Home Shopping Network audience or the RNC), but a speech of good content, presented poorly, is almost always DOA. Unfortunately, watching my fellow presenters strut their stuff, I think I may have to agree. Dull speakers kill the message.
The instructor seemed to think I was one of the more amusing speakers in the class. Apparently, I have a good sense of humor, by Microsoft standards. I imagine this is like being tall by Pygmy standards.
