Because this is possibly the lamest idea ever, I'm not going to bother with the whole week-long thing. Instead, you get one big loooong mega-lame post. Please don't leave me, I'm going to try to post something worth reading this week.
(As you will note, this is Sunday, not Monday.  I just wanted to get the thing out of the way but didn't want to NOT post after I said I would.)
