Some professors do that for effect (Or so I believe). Otherwise, all their students would be falling into comas. My organic professor in college was a purist; he let the science do the talking. Probably why I needed to pull an all-nighter for a "B".
This prof sounds like she needed a serious sexing. Or maybe just some valium. Or both.
