Bill,
One year, when I was a kid, my pops put a dummy on the front porch with a crazy halloween mask for the face. Then, Halloween night he put on the dummy's clothes and mask and sat on the porch. Since most of the neighbors were used to seeing the dummy all October they had no clue it had been replaced by my pops. I'll never forget watching him slowly reach out and grab the kid that lived across the street. The kid literally pissed himself. It was hilarious and sad at the same time. He also scared quite a few tough teenagers. Great times.
