Do this one to someone you absolutley hate!! If they are wearing a jacket, coat, or something with a hood, chew some gum up real good, and stick it in there. When they put on their hood (if they do put on their hood) the gum will get stuck all up in their hair! It works! They had to get their hair cut to get it out! (and if you are ever in a situation where you would have to tell them how to get it out, peanut butter works!)
