circuit is a dog genetically engineered to conduct electricity and control it any way he pleases, with a belly that's ir-resist-able! as long as he trusts you, you won't get an electric shock when you pet him, you'll only feel minor static. if you lay ontop of his belly, you feel a small vibration, like how massage chairs vibrate, and that's just because he likes you. after all, he did let you lay on his belly.
