round up

I recall an infomercial a few years back for a little plastic triangle that stuck in a corner, between two walls, to make a small corner shelf. I don’t remember the exact name of the product, but I do remember that the commercial exhausted all the obvious self/shelf puns: “shelf esteem,” “shelf confidence,” “shelf defense,” “shelf-employed,” etc., etc. So I’ll forgo I’ll the all the opportunities this topic offers for shelf-referential humor and just get down to business.
