12 years ago I was the project manager for a HVAC and refrigeration company. One of the installers was out sick. So I'm at a customer's house with the new helper/apprentice. That day we were pulling wire for two circits. A gas funrnace and ac condenser. I'm showing this kid the buss bars in the main panel. Explain to him three f-ing times don't touch the buss bars that the breakers connect to. Theyre "hot", will shock the sheet out of you. The *pretty boy, let's call him David, sticks his hand in the main panel and proceeded to put his finger right on the buss bar.... intentionally!!! He stands there convulsing for a second or two, being electrocuted, then falls on the ground(lucky for him). Lays there shaking for several more seconds recovering......then looks up at me and says "that really hurt, it shocked me". That day I was exposed to a new level of stupid never seen before.
