Total drift but thinking of poking things in slots reminds me of a good laugh a few years ago. I was on a course which mostly had kids (16yr olds) but there were a couple of mature students on it. One of them was very well respected as being serious, concentrating on learning, etc. generaly a model student. It was to the amazement of all of us that in a programming class he suddenly called the tutor over explaining he had got one of those geometry triangle things stuck in a floppy disk drive. Even the tutor laughed.
