Holy crap, that's like the demonstrations on airplanes when they teach you how to put on your seat belt.
And for the people that don't think the MotionPlus is actually glued to the jacket, don't you think they would've shown a step that said "Insert MotionPlus accessory in to the hole in the Wii Remote jacket"?
And since people HAVE thrown their remotes into their TV's and broken them/ hurt themselves, Nintendo has to make sure it can't happen anymore. That's why they brought out the jackets in the first place, now they just found a way to make it mandatory.
