I remember when I was a teenager I had an older friend who developed a very deep voice, but didn't like to use it much. One time we were all at a local movie theater, and several kids were acting up a few rows ahead of us. They were putting their feet on the backs of chairs and throwing popcorn and talking loudly.
My friend decided he had enough, so in his loudest Stentorian voice, he yelled "Put your feet down NOW!". It was like the voice of God. I never saw feet come off the back of theater chairs faster. It was just something about the tone in his voice that put the fear into them.
