Mike Rowe has tried over 300 odd occupations on Discovery Channel's *Dirty Jobs*, but what was the scariest job he ever held? "Window cleaning in Hawaii," he tells Rachael. "It's one of the only places in the country where they're still allowed to clean windows from a bosun's chair. It's not a scaffolding like you see here in New York; you have to throw your feet off the side of a gantry crane, put your feet on the swing and then lower yourself into it and tie yourself off. So it's very ... sporty." One job that Mike is gladly taking on is taking *off* his jeans to help fight breast cancer!
