On paper, having a Halloween Honor Bowl full of candy set out for trick-or-treaters is a great idea; you don't have to sit out all night waiting and the neighborhood kids are trustworthy, right?

I put out a bowl of candy with a sign that said, "Take One, Please." How long did that last? Here's the video.

Keep an eye on the vampire towards the end:

Apparently ghosts and ghouls are above using the honor system. Feel free to try this experiment yourself, just don't expect the candy to last very long without someone there to hand it out.
