Humour in the Darkest Hours

So today I gave my last lecture to the first year scientists/engineers. At the start, as is customary, I handed out questionnaires. As a student I was always really mean on these, but -- thank god -- they were quite kind to me. I've been smiling all afternoon because they were really nice, though how much of this is due to my relative youth -- I could be half the age of most of the lecturers -- isn't clear.

Anyhow, my favouritest one was this (they've been told I'm a Dr, which is premature):

What did you like about the course?
Dr Hepworth who managed to provide humour in the darkest hours.

Whether that makes me more of a clown than a nice guy isn't clear, but there you go. I liked it.
