You've got to go trick or treating as troll Jericho. When someone answers their door, just barge straight passed them and strut around their house saying 'Yeah baby!' and 'Oh yeeeeeah!' over and over before leaving without even acknowledging them.
Of course, if you're in the US then you'll probably be shot.
You could do it to your friends or people that know you though. Just don't explain your actions until the next day at least.
Season 4 of Breaking Bad marathon. If guisers show up, I'll greet them with a Patrick Bateman cosplay (slicked back hair, spits of blood over my face and suit, and comedically holding an axe in one hand behind my back. Even if they don't know who he is, they'll laugh at it regardless.)
I know, someone actually happily handing out candy to guisers without shunning them or treating them like scum. Fuck me, right? -_-
