What Is The Hard To Find Toy This Year?

Every year it seems as if there's one toy that no one can get their hands on.  When I was a kid, I remember seeing grown adults fighting over Cabbage Patch Kids.  More recently it was the Furby.  I had to wait until April to get a Wii when it first came out.

My wife and I were blown away with one of our first shopping trips early in the season to see that the Teenage Mutant Ninja Turtle stuff was cleared off the shelves.  Every store we went to was the same.  Not a single turtle was there.

So what is the big one this year that's hard for you to find?  Maybe we can help each other out here.
