Terrible Southern or Texas accents. They are more often terrible that good -- usually it takes a native -- but the worst one ever was on the sgt major in Generation Kill.
Nobody, I mean not even the most idiotic trailer-dwelling backwoods yokel talks like that, and i have hung out with idiotic trailer-dwelling backwoods yokels everywhere from the Sam Houston National Forest to the hollers of West Virginia.
(Not so fun fact: Sgt Major John Sixta, the guy portrayed here, was a pedo. He was convicted for raping a friend's 12-year-old daughter after returning from Iraq, and you can't blame PTSD, even if you were so inclined: after that conviction, two California women came forward from decades ago that landed him prison for 30 years.)
Looks like he was maintaining grooming standards before, during, and after the war.
Anyway, he has an unusual name and so he was easy to research. (How many hillbillies have last names like Sixta, anyway.)
He is from the Kansas City metro. Maybe there is some linguistically isolated suburb up there where the accent makes Yosemite Sam sound like Al Michaels, but I doubt it. Simon and Burns apparently just thought it would be funny to give the biggest asshole in the battalion a horrible fake Southern accent. And that makes me surly.
This bothers me a little less, but whenever there's a scene in some shithole bar on a show like Justified, the background music is always waaaayyyyy cooler than it would be in real life, but no, the little hillbilly Mafia that runs Skeeter's Beer Joint are playing Steve Earle or the Drive By Truckers, and not Toby Keith and Garth Brooks.
This good buddy mine will eject on a show if it does this more than once. Or even just once, sometimes. The Wire almost lost him when there was the scene in the dockers bar featuring the Nighthawks, a criticially acclaimed DC roots-rock band from the '80s but today pretty much forgotten weekend warrior biker dad blooz. And then it did lose him when the cops -- Black and white, everybody -- were always singing along to the fucking Pogues at wakes for dead cops. i kinda thought maybe that was possible, given the stereotype of the Irish cop, esp on the East Coast, and how it seems like every cop killed in the line of duty has the bagpipes blaring somewhere in the vicinity, but he just wouldn't have it. And he was right and i was wrong -- Simon and Burns just thought it would really cool if that was the way cop wakes were.
