I used to watch the show when it was on Discovery. It was usually really gross, but fun to watch. 
A lot of the jobs were pretty dangerous, too. There was one where a lady was running something like a reserve for wild monkeys, but the little buggers were really vicious and would attack for almost no reason, and a cameraman got savagely bitten on the leg and to leave (he turned out okay). Most people think monkeys are cute, friendly and lovable (and I guess they are most of the time), but they've been known to kill people.
Making home-made chocolate for a living like they did one time is one dirty job I wouldn't mind having, though. Even though I'd probably be so sick of chocolate I'd never want to eat it again.
