Needs Help: For Want Of A Nail

The pic right now is a literal representation of the trope name, with nothing to do with the trope itself. I understand why; this is a difficult one to picture.

I was just hoping that by applying a forum full of tropers, we could think of a way to do it. I'm not sure if we'll be able to, especially since I can't think of one right now, but I thought it was worth a try.

(Personally, I don't like literal representations of a name in lieu of an actual pic of a trope, but I understand that's a minority opinion.)

Declining to open.

The current image was chosen over an even more literal one in this thread; "I don't like it, but I don't have any suggestions" is not sufficient for a page image that was chosen by IP.
