While trying to Google up the Barbie 12 Dancing Princesses website for my daughter over the weekend I stumbled upon "Will It Blend?", where the folks at Blendtec attempted to blend two Barbie Dancing Princess dolls in one of their entry-level Total Blender appliances. Did they in fact blend? Well, you'll just have to watch the video to find out, but I can say that rather than running away screaming in horror my daughter enjoyed it thoroughly.
(So I guess I get points for subverting the princess meme, if nothing else!)
