If I wanted to craft the worst metaphor you’d see all week (on this site, at least), I’d say the following:

Dark Corners (2006) demonstrates that now matter how gorgeous and durable your collection of yarn is, it doesn’t mean a damned thing if you don’t knit the stuff into a sweater.”

But, of course, I have no ambition of presenting you with a really bad metaphor.  So that comment above?  I never said it.  Must have been a bad dream.
