Harumph!
NightLine just showed a visually striking snippet of some "Human Foot Print" special coming up. They used little rubber ducks, of the type that Martha is fond of collecting, to demonstrate how many showers the average person takes in a lifetime.
28,433.
So what about the foot print of 29,000 little rubber ducks. Computer generated or enhanced? Or did National Geographic buy all the duckies and then send them to a landfill?
