Occasionally XKCD hits the spot - we teachers feel rather unloved sometimes. I lost track of the number of people at these weddings who said things like 'you must enjoy your three month summer holiday' etc.
For the record: we don't get three months off. We mark all the essays and dissertations. Then we second-mark more of them. Then we mark the resits. Then we try to do some research, and write next year's lectures.
