Yeah I have..
Was up some ladders doing some re-wiring in the kitchen and forgot to turn the elecricity off (yeah.. i know..) and cut a cable with some scissors, next thing i knew, I was lying on the floor at the opposite side of the room.
Apparently the shock blew me off the ladders and in to the wall opposite. It took a chunk out of the metal blades in the scissors and the bang was so loud that it literally scared my budgie to death.. Poor Bluebird...
I'm good now though
