Method one: Hide in the bushes near a dark-ish house that's giving out candy. Wait until you see a kid with no parents walking with them. When they get the candy and the person shuts the door, grab the bag and run.
Method two: Walk through the streets into a crowd of kids by themselves, grab bag. Keep walking.
Method three: Push kid over, grab bag. If parent is nearby, feel free to do the same to them.
Enjoy. Feel free to post your idea's.
