Do you watch the Discovery Channel? I love the program called Dirty Jobs with Mike Rowe. He does some of the dirtiest jobs known to man. In one of his early segments he actually went down into a sewage pump station and cleaned and scraped the grease and junk off the walls.
Makes you think about what you eat if that stuff ends up on the walls of a pit, whats going in our our stomach?
What is the dirtiest job you have done?
