I wore one on halloween many years ago. I just sat off to the side of our front door next to some yard debris. Every once in a while I would say something to the kids like "don't forget to say thank you", "give one to your brother", and other stuff like that. I didn't want to scare any kids, just had fun with them. Kids would look near the door for an electronic speaker, and thought it was a guy with a microphone. It was quite a bit of fun.
