Betwixt

Except once for Ted and once for Myk, there have been no guesses in comments. I'm assuming that people are guessing but not recording, which, not only is fine, but reasonable in that this is just supposed to be a diversion, which may spark further interest once in a while. So I think a better format is to give the answers in the first comment when the question is posted. So there will be no one-week delay. By then you have forgotten your answers anyway. By the way, as Myk pointed out, these are not really meant to be a test of knowledge--more like a parlor game. You may have a good idea about one or more of the items, but luck, or lucky reasoning is most likely needed. Here's an easy one to get started with the new format:
