From the movie Shawshank Redemption. Tim Robbins' character, Andy Dufresne, secretly digs a tunnel in his prison cell, and hides the dirt and cement from the wall in his pants legs. To get rid of it without anyone knowing, he takes a stroll out in the yard every day, and with every step shakes a little bit out at a time.
