Here's a fun one for you (but needed for an actual serious reason)...
What are some of the worst-selling toys in North America this
Christmas season. Of course, your Aunt Judy's walnut cookies may not
sell a lot, but I'm looking for toy products which either have a
strong brand or have been marketed lots, but still aren't selling
worth a damn.  Would need basics: Product name, web site, price, and
ideally why it's not selling...

I'll bet merchandise related to Michael Jackson has taken a downturn
lately (unless collectors are snatching it up).
