Whirled series?

This question has has bothered me since the very first -- oops, no, make that the second -- Weenie book hit the shelves.  They are treated as a series, but don't have any common characters or setting.  They share a format (short story) and a loosely-defined genre (weird), but little else, beyond their amazing covers.  (Thanks, Bill Mayer.)  So, I figured I'd poll the smarties who read my blog.  Please feel free to include a comment (even if you don't select "other").
