Best halloween prop is to have a very decorated front yard with all the fixings. Then at about 4 am, grab either a mask or a straw sack, climb a tree in your front yard with a rope tied into a noose. Tie it to the tree and then hang yourself. First day, people will notice and start to complain about the morbid decoration. A couple days later, cops will show up to complain. After getting no response for several days, they will decide to remove the decorations themselves. That's when they realize that the "prop" that your neighbors kids had seen the past couple of days wasn't a prop and was actually your rotting corpse hanging from a tree.
