Well, I had a Chemistry teacher once who claimed that "There's a little pyromaniac in all of us." I lived in Texas at the time, and he, as well as being a good ol' boy, was a pyromaniac in all due fashion. He taught at our high school across the hall from a woman who had had a class with him in college. When they were lab partners, he had reportedly, 'accidentally burned' her on several occasions.

Nothing really bad had happened to her, but the fact that he had burn marks on the ceiling above his classroom, coupled with the fact that he admitted to having burned holes in his clothes during class, compounded by the fact that he would sometimes get big chunks of pure sodium, and toss them in a bucket of water during class, was indicative of his mental state (i.e. Pyromaniac). He was a lot of fun too.
