Also, you know, I graduated from law school and stuff (which...might have been another type of cclose call, and which probably deserves its own post).
Had to be back when I was in math grad school and they were doing construction near the math building. They were blasting rock between our building and another. Whenever they were ready to blast, there would be a warning horn. Because of where my office was located, and because mathematicians are just a little insane, people would hear the warning horn an drun into our office (I shared it with three other grad students) to watch the people with the dynamite.
One morning, I got an almost frantic call from one of the department secretaries. The dynamite had shattered our office window. My desk had been right in front of the window, and some of my stuff was destroyed. But fortunately, *none* of us were in the office, and no passers-by had been lured in by the siren ssong of the warning horn.
It was really unusual that none of us were in the office at that particular time. But given our habit of ignoring the horn, it was certainly a good thing!
