Need Help Smiling?

Apparently, there are some people in this world whom have a problem smiling correctly. For those people, we have the solution: the Beauty Smile Trainer.
Supposedly, this little piece of rubber is supposed to help improve your ability to smile widely and more amicably. How, exactly? I have to imagine a piece of plastic in your mouth isn't going to make your smile any better or worse. I gotta believe your smile isn't going to look very good while you hold a piece of rubber in your mouth.
Seems like a waste of money to me. Thankfully, this gadget is only available in Japan. Or at least it looks that way given all the japanese writing on it. Either way, leave a comment and let me know what you think!
