See if you can top this! Back in my high school days, my little rock band was playing a New Year's Eve party with a rented PA. First song into the night, and we're really jammin'. The 1st chorus rolls around, and I step up to the mic to sing backup and WHAM! Blue and white lightning arcs from my mic to my mouth. I hit the ground, the PA goes out and all the lights in the house go off. Turns out the rented PA wasn't grounded properly somewhere. My hands on the bass + my mouth 2 inches from the mic grounded the whole affair rather nicely. The fuses were blown in my bass amp and the PA, and the breaker tripped in the house. Throw in an eraser-sized black scar on my upper lip (which I sported for a month), and it was a heck of an evening. Luckily someone at the party was studying to be an electrician and had some tools in his car. He had us properly grounded and rolling in under and hour. The show must go on! But you can bet I didn't sing any more backup that night.
