Growing up, my dad always got a kick out of scaring trick or treaters. He would prepare for weeks, different ways to try and get little kids to cry. that explains a lot about my childhood in general. One of his favorite pranks was setting up a scarecrow with a CB radio (80's technology). When those freeloading trick or treaters would show up, he would scream into the radio and send the little kids racing down the street. The upside, we always seemed to have leftover candy. Check out some easy pranks you can play on trick or treaters this Halloween.
