I love that! It's how it will be known from now on. Now for my cable continuity tester (a.k.a. a wire cutter), and my soak testing station (aquarium).
My colleagues, after a while, in a former job knew better than to come to me with stuff they "weren't sure of if it was broken." They always came away very sure it was (where hours spent "fixing" things cost more than a damn spare).
