Object:
wear a strange piece of clothing or hat (or something completely out of character, like wearing a wastebasket for a hat)
Good morning, boys and girls. What do you think of my new piece of clothing? (Let them answer.) It's pretty strange looking, isn't it? I might wear this one time and get away with it. If I wore this all the time, you might think I was strange. My family would become pretty concerned about me. What do you think would happen if I wore this everyday for one week? (Let them answer.) I think I know what would happen. My family would probably sit down with me and have a long talk about how I've changed. They would ask me if something were the matter with me.
