Covering your hands with glue
Letting it dry, to peel it off, like a thin layer of skin
Sticking pins through the top layers of your fingertip skin, to make a wimpy Freddie Kruger
Watching hydrogen peroxide bubble on your scrape
And then, picking off the scab
Unbending a paperclip, to fashion a makeshift retainer for your teeth
Swinging your arms around in the sideways helicopter, so it can make you run faster
I'm sure I'll be adding to this in the comments.  Please add too, if you can think of anything
