I have one of those little buggers, and they do work like that. My buddy grabbed it one night and wanted to check it out. He put it to his neck and was going to zap himself, i told him your going to regret that don't do it. My other buddy was standing there laughing at him and said let the dummy do it. Well my buddy did'nt like that comment, so he zapped him in the mommy daddy bag and i sware he must have jumped 5 feet in the air, well the fight was on and they ran around the house zapping each other. Once i got off the floor from laughing so hard i finally managed to get the taser back from these children and settled them down. My roommate at the time was lecturing me about encouraging these two when they're drunk. I admit i was curious and wanted to see someone use it on someone other then me. I may have been a little guilty.
