Prank for Halloween?

I am one for pranks. Doing them, not receiving, of course. I know, I'm a wuss like that.

I have done a number of pranks for Halloween. One of my favorites was dressing up as a scarecrow and sitting on straw bales as a teenager. When someone would walk by I would reach out and touch them. From there I would just watch the fun unfold.

Watching pranks on YouTube is especially fun. I think this particular one would be good for Halloween. Not much effort, but enough reaction to put a smile on your face.
