Freezing down there

Courtesy of The Peripatetic Engineer, this (and finally true last night):

Did you hear about the Cajun who went to Hell? The devil, assigning him the usual punishment, put him in the pit where the heat was melting others. The devil came back sometime later, surprised to find the Cajun just sitting around, not even misting, much less sweating. "How come you're not so much as sweating here, where everyone else is screaming for relief from the heat?"
The Cajun laughed and said, "Man, I was raised in the bayou of Sout' Looziana... Dis 'bout lak May in Lafayette to me!"
The devil decided to really put the Cajun through it. He put him in a sealed off cave in the pit with open blazes and four extra furnaces blasting. When he came back, days later, the Cajun had barely begun to bead up with sweat. The devil was outraged. "How is this possible!? You should be melted to a shrieking puddle in these conditions!."
The Cajun laughed even harder than before. "Hey, man! I done tole you. I was raised in Sout' Looziana. You tink dis is heat? Dis 'bout lak August in Jennings!"
So the devil thought, 'alright, a little reverse engineering ought to do the trick.' He put the Cajun in a corner of hell where no heat ever reached. It was freezing and, to add to the Cajun's misery, he added massive icebergs and blasting frozen air. When he returned, the Cajun was shivering, ice hung from every part of him, but he was grinning like it was Christmas.
Exasperated, the devil asked "How is it possible?! You're impervious to heat, and yet here you sit in conditions you can't be used to, freezing cold, and yet you're happier than if you were in heaven. Why?"
The Cajun kept grinning and said, "Looks lak Hell's froze over. Dis means de Saints won da Super Bowl!"
