Ha! I had a customer who thought that a family member had bugged the home and was looking through the surround speakers in the media room. So she place plastic target bags over the speakers. I took one of the bags and put it over my head and talked to her in a normal voice. I asked her if that the bag had silenced my voice at all. She looked at me with disappointment and said no....This lady was a very intelligent doctor! LOL. I feel the smartest are usually the craziest.
