Nope, they sure don't... not that I've seen yet.
It's usually in a smoker or smoke pit... and oh is it delicious. If y'all ever get to Austin, you have to try Rudy's Extra Moist brisket. To die for... My wife's mom prefers veggies and rarely eats meat and after having a taste of Rudy's she said "I'd eat that pretty regularly if I lived here".
I've done a chuck roast in a dutch oven (inside my electric oven at home) at 200 degrees for about 4 hours before... It came out wonderful. I've never heard of anyone here in Texas doing brisket in one... but like I said, it looks tasty.
