In a similar vein, it is absolutely amazing how much fun you can have at a juvenile prison on Halloween night with one of those hard plastic Frankenstein's Monster masks with the eyes that glow in the dark.
After lights-out, suspend it by a couple of fishing lines & lower it from the windows of the floor above so that it attracts each one's attention, banging in the breeze against the bars over his window.
You don't know what pandemonium really is until you've seen the result first hand.
They think they know there aren't any such things as monsters. But when they see it, and have no way of accounting for it, it gets primeval.
WAY better than the old rubber snake in the bathroom.
