This is all from RE4.
I'm going to sit on my friends porch as a ganados. He will be in the back with a real chainsaw w/o the blade, dressed as Dr. Salvador. I'll have the soundtrack playing, once someone gets on the driveway I'll switch to the fight music, I'll yell at them like in the game and my friend will start the chainsaw and run at them from behind the house, I'll run inside and get the clothes on to look like the merchant, once my friend runs at them I'll switch to the save/merch safe music and they'll come to the door, I'll do the "What are ya buying?" and give them the candy.
Sounds epic no?
