Years ago I worked in a TV store, one of the owners was always leaving a soldering pen on the edge of the bench. Whenever he reached over for a tool, he would set fire to himself.
One day the hardware store up the street had these 3 pound fire Extinguishers on sale, we bought one, went back to the shop, grabbed him and cable tied it to his leg.
That was about the third time I got fired from there.
