My dad did that for Halloween one year, he put a tarp over my babyswing, and when the kids would ring the doorbell for candy my parents friend would open the door, give them the candy, then when the kids turned around my dad would pop out with a mask on, a suit w/ red paint, and a chainsaw (of course, w/o the chain)...I was only like 3yrs old so I didn't see it, but the next year my dad didn't do it because he wanted to see me trick or treating, and I guess a lot of the kids were upset that he didn't do it.
