Stand in the front yard completely immobile in the early evening facing the direction of the street wearing a Reaper outfit with a deformed-face mask and bricks tied underneath my feet so I look taller, and then when someone(s) who’s not a little kid comes up to the door, leave my spot and stand at the bottom of the stairs completely still, holding the pumpkin with the candy in it until they turn around.
I only did it before for one Halloween, but the reactions are priceless. My all-time favorite:
[Sun is starting to set]
A group of 4 people, 3 teenagers and 1 woman come to the house and the woman stands on the sidewalk while the other 3 walks up to the door.
>I start walking from the yard to the steps so I can stand there waiting for them, when:
Woman on the side-walk: * SCREAMS *
3 kids: * Turns around and screams*
1st kid: * Quickly hops over the side of my porch into the drive-way like Spiderman*
2nd kid: * Quickly moves back to the other end of the porch *
3rd one (Girl): "Oh my God guys he’s not real!" [Laughing]
Me (In the best down-syndrome voice I could do): "P-P-Purrrrtyyy…"
3rd one (Girl): * Screams *
Me: * Takes off mask * "Relax, I’m human. Everybody? See? Not gonna kill ya."
Everyone calms down and gets a laugh out of it, and I give them their candy
Woman: "You’re lucky I didn’t have my pepper-spray with me, 'cuz in the spur of the moment I might of had used it."
Me (Under my breath): "And you would’ve gotten drop-kicked with these bricks…"
Woman: "What was that?"
Me: "I said, then I guess I’m done with the tricks! Happy Halloween. :>"
