Haha they need to make that into a commercial. You know how many guys would just buy it to see their girlfriend do that.
I personally think it's pretty wack. When I turn on my Wii, I want to feel like I'm doing something BAD for myself, not exercise.
She does not even have that good of a body and I bet her face is not that great either. Plus... When you have a girlfriend you can just ask her to shake her ass for you and more... No need for wii
