The cost of a piece of metal in your eye.
Lol my bad, it hurt like a sun of a biscuit.., but i cannot imagine one of those little "wire death minions" sticking the boys... And i wrote that wrong lol i was tightening the exhasut manifold, my hand was pinned between the manifold, and the solenoid,which was negative(block) my hand:( and positive(solenoid).. The extension i used wasnt short so no matter how i turned or tried to pull away, i was getting zapped and could smell my skin burning while it felt like i was getting smacked with a hammer numerous times.. I even seen what i thought was small lightning shootin outta my hand lol..
