You have to hand it to the History Channel, they know a ratings monster when they see one. And, really, there's nothing about a gang of Cajuns chasing gators in Lousiana's swamps that doesn't sound like it would command attention, even if only by way of ridicule.
The insta-hit Swamp People takes the danger of the Deadliest Catch and inserts salt-of-the-earth people into a far less exotic locale. The risky task they undertake seems thankless, but the men hunt down their thrashing prey with gleeful flourish, uttering catch phrases like "choot 'em" that leave haughty viewers to ruthlessly poke fun at Southern speech patterns.
It's like a redneck safari where your tour guides are unapologetic, uncouth, and really damn good at what they do.
