Host Mike Rowe demonstrates some of the dirtiest jobs that have to be done to keep the world fed and cleaned. Mike ventures underground into a greasy pit of sludge to join an environmental company that recycles the gunky grime. Plus, watch as Mike is "bee-deviled" during a stint as a honey farmer. In Hot Tar Roofer, Mike lands on a church rooftop and learns how to melt down chunks of black tar for the purpose of roof repair. Later, he takes a job as a house mover and tunnels under a 60-ton house, before jacking it up and placing it on giant wheels.
