You might not even realize someone is using voodoo on you!
You'd think "Dang, that really hurt, my hand must've slipped. The voodoo doll hangs from your wrist by a little chain and is the perfect touch to give this costume a really creepy edge. After all, it certainly looked intentional, the way you stood up, walked over to his desk and threw it in his face." Your day goes on, seems normal for the most part, and then all of the sudden while at work, you throw coffee all over your boss! You didn't try to, your hand just lurched out, out of your control!.
