I had nothing to do,,,I saw the camera sitting there and I was already chewing gum...Idea! I found my tri pod and I set the camera up. I begin chewing my gum, blowing a bubble or two...But then I start to stretch my mouth showing my teeth and gums, the back of my throat. A mouth tour clip with a mouth full of gum. This is what I do when I have nothing to do, LOL
