Many years ago, I worked on the production floor of a print shop. (I wasn't actually doing print work. I was a designer, but they hadn't built out the offices yet, so my Mac was literally sitting on a desk in the middle of the print room floor.)

Do you know how loud "Butterfly Kisses" — apparently the #1 through #40 top song during the time I was doing this — has to be cranked to make it audible over a web-fed offset printer and cutter? I do.
