Sticky Hands

Get some classic Elmer's Glue and squirt a dob of it (about the size of a nickel) into the palm of your hand. Rub both hands together until the glue becomes very tacky. Hold your hands tightly together for a couple of minutes before pulling them gently apart. You should be able to peel off bits of glue. Do this until all the glue has been removed. At that point, you shouldn't want to self-injure anymore.
