One day, an engineer stepped gingerly into the entry way of my office
and asked, "Bob, do you have a Siliconix catalog?" I replied, "Sean ...
you're standing on it." He looked down and, indeed, he was. He was
impressed. But I knew right where it was, because I had recently tossed
it over by the doorway so I could then put it in the bookcase by the
door. Sean just happened to walk in before I put it in the bookcase.
