20 Things to Write
3) Put a sticky note under a mouse (for a computer) and write GOTCHA on it. It'll make it not work and someone will go crazy trying to figure it out
9) Go to school early and write on the white board "(your name), YOU are the chosen one!" Then leave and enter the class normally like everyone else.
16) Write nothing on a piece of paper. Act like there's a big fat secret in it. And give it to a person.
19) Write on a piece of paper "There are foot steps on the ceiling" pass it around and watch them look.
