It's too easy to make jokes about this one, but like the Wii and all it's...stuff, I'm sure we'll grow up and accept it. It's a controller that you put the Wiimote into and literally squeeze. It's like the Wii Fit board, but for the upper body.

But the point is that it's actually difficult to push together, so it functions like an exercising tool anyways. What the hell it can be used for other than possible in-game groping and yet another Wii ____ game, I don't know, but I dare not venture further down that path. It is dark and filled with vans and scary men with candy.
