Flickr user Rob Cruickshank made this little contraption called Lil Sparky:
Putting the "cute" in "electrocute"!
Powered by a 9v battery, it delivers just a little jolt.
Endless possibilities for fun- imagine if the one who loses at Scrabble, or doesn't do the dishes has to go to "the chair"!
Also good for trick-or-treaters who show up without a costume.
