Say; Damir, who did that song..Rock and Roll High School? You know..Rock Rock, rock and roll high school. Lots and Lots of stories on that subject. When I was a kid they used to let us do arc-welding in shop. The safety rule was if anyone was welding in the booth no one could open the curtain until the red-light went out. Of course that meant total privacy which of course meant the perfect place to indulge in improper activities. And the fumes from the welder masked any other smells. Took some guys an hour to draw a single bead.
