I always thought low voltage stun guns and/or cattle prods would be a good idea for people with kids. I remember I was at one of my "nephews" birthday parties, he must have been turning 7 or 8. There were like a dozen and half kids just running around crazy all hopped up on soda and birthday cake. The parents kept on running around crazy themselves trying to keep after all of them (we were at a park with a huge playground). I just sat there with my "nephew's" actual uncles drinking beers and thinking how good of an idea low voltage stun guns and/or cattle prods would be for such situations.
