Yes,  as a matter of fact I *am* replying to myself...

This is a story my mom told me. She saw the whole thing. One day my dad
was repairing this giant Muntz TV, back in the 1950's. My dad had no
electronic training above being a prop-plane mechanic in WWII (Army Air
Corps). So my dad took off the back, defeated the interlock, and he
began probing inside with a screwdriver. All of a sudden there was a
snap, a boom, a flash, and my dad flew across the room as if shot out
of a cannon.

He was OK after a suitable attitude adjustment.
