I've noticed a similar problem. I have a macbook pro and a macbook air and whenever I have both of them plugged in and am touching both of them at the same time (usually one arm laying across both of them) I can feel where my arm is touching the laptops start to hurt/burn. I figured the electricity is now going through my body, but assumed it was a problem with the laptop, not necessarily the electricity.
