When I was just a boy, I went to the park one winter day, and was trying to climb up a metal slide, I just couldn't make it, because it was so slippery, so I decided to use my tongue as a grappling hook, and pull the rest of my body up the slide with my tongue. I stuck my tongue to the slide, and slid back down, leaving the skin of my tongue at the top of the slide, and me with a mouthful of blood at the bottom.
