Pencils whose lead slips out of the wood when you're sharpening the point with your knife. One of those unexplained mysteries...this get dropped too many times I wonder? They need to tighten The Code on pencil manufacture? Some over-worked machine in Muncie, Indiana distraught over the unwashed coffee-maker in the break room? What? Do they make pencils in Muncie? Yeah, give me a handful of those Number-Two Muncies. Top-notch for me, nothing but the best. Or one more recent...say you're about to nail something w/the nail-gun, you've got the tip of the nailer just-so...a helper is straining, pushing on a stud, and you're about to pull the trigger to pin it in place? Out of nails. You and the help are all set to participate in a moment of glee...nailed that sucker...this is what separates the men from the boys, yes sir...they don't build 2x4s like they used-too...and you run out of nails.
