A few months back my co-worker Dave did a blog on hidden talents. Yes, he has one, no I don't...that I know of anyway. However, I found another video of a little girl that has one. This girl sings Twinkle-Twinkle Little Star with her mouth completely closed. You can understand her words clearly.

I think she has ventriloquism in her future. I tried it and it just sounded like mumble. You know you want to try, so go ahead.
