Eating fossils
The rock lying by the roadside did not look like much of interest at first: a rather nondescript limestone, with little more to show to casual observation than a few vague blotches.  Anyway, old habits die hard, so I picked it up, licked the surface and put it, and my hand lens, to my eye.  The memory of the shock, and the thrill of minor discovery, is still fresh.
