My mask (left) that I've had since '79 is just real enough that it provokes some interesting reactions. I worked a haunted house one Halloween and was punched 3 times! Had a great spot in a hall closet with foot triggered light, long dark hall, lean out right in front of them and hit the light! The way the eyes are cut I can drive with it and that can be pretty humorous at a stop light.
I can see getting punched ... some people react badly to what they think are near death experiences.
