Walk/Watch

When I go to the gym, I often watch tv on the treadmill, as it helps pass the time and distracts me from the absurdism of running to nowhere.  Yesterday I observed an application of this idea that I had never anticipated.  I was walking Mollie in the park when I heard the sound of recorded dialogue.  I thought it was a radio at first, but then I saw a man walking along the path while watching television - not on a little iPod, mind you, but a full dvd player with a laptop-sized screen.  What was he watching that either couldn't wait until after his walk, or which provided such terrific motivation while walking?  Married With Children.  I find it remarkable that someone would own a dvd of Married With Children, much less take it for a walk.
