When he was a graduate student, one of my advisors used to smoke cigarettes while lecturing (this must have been the early to mid 70's). Anyhow, one day he was giving a lecture on Joyce's Ulysses and said he felt this horrible burning sensation coming from his right thigh. That's when he suddenly realizes (no joke) that he had set his own pants on fire. After semester's end, the chair of the department calls my advisor into his office and asks him if it's really true that he set his own pants on fire, in class. Apparently the end-of-course evaluations had a question about the most memorable lecture or most memorable moment in the course and almost every single student had said something along the lines of "The lecture on James Joyce's Ulysses when Professor XXXX set his pants on fire."
This is apropos of nothing, but it's a great story.
