These Halloween scare mazes are the best.  You really have to use them on the right person and get them extremely focused on the screen.  If you can do that, you can sit back and enjoy your friends freaking out.  This is the best reaction I have seen so far.  Not only is he left screaming "why?" and crying, he also loses control of some key body functions.  Hard to tell if it's fake or not but bravo if it's acting.
