LOL! Steal their candy and redistribute it to all the other kids, keeping 35% (corporate tax rate) for "administrative costs."
Yep, answer the door, and say, “oh kids it’s Barack Obama! YEAH!! We are gonna take all your candy, just like Obama wants to do with MY money...and REDISTRIBUTE IT!! YES WE CAN!!! YEAH!!! Right kids, we want to help those kids behind you that may not have as much as you do. Here are a few pieces for yourself...”
Or YOU wear an Obama mask, and TAKE the kids candy when they get to the door, and redistribute it...as a civics lesson....and a Halloween trick!
