Two guys from Buffalo, NY die and wake up in
 hell.  The next day the
devil stops in to check on them and sees them
 dressed in parkas,
mittens and bomber hats warming themselves around
 the fire.

The devil asks them, "What are you doing?  Isn't
 it hot enough for you?"
The two guys reply, "Well, you know, we're from
 Buffalo, the land of
snow and ice and cold.  We're just happy for a
 chance to warm up a
little bit, you know."
The devil decides that these two aren't miserable
 enough and turns
up the heat. The next morning he stops in again
 and there they are,
still dressed in parkas, hats and mittens.

The
 devil asks them again,
"Its awfully hot down here, can't you guys feel
 that?" Again the two
guys reply, "Well, like we told you yesterday,
 we're from Buffalo,
the land of snow and ice and cold. We're just
 happy for a chance to
warm up a little bit, you know."
This gets the devil a little steamed up and he
 decides to fix the
two guys.  He cranks the heat up as high as it
 will go.  The people are
wailing and screaming every where.  He stops by
 the room with the
two guys from Buffalo and finds them in light
 jackets and hats,
grilling sausage and drinking beer.
The devil is
 astonished,
"Everyone down here is in abject misery, and you
 two seem to be
enjoying yourself."
The two Buffalonians reply, "Well, ya know, we
 don't get too much warm
weather up there in Buffalo, we've just got to
 have a cook out when the
weather's this nice."
The devil is absolutely furious, he can hardly
 see straight.
Finally he comes up with the answer.  The two
guys love the heat because
they have been cold all their lives.  The devil
 decides to turn all the
heat off in hell.
 

The next morning, the temperature is below zero,
 icicles are hanging
everywhere, people are shivering so bad that they
 are unable to wail,
moan and gnash their teeth.  The devil smiles and
 heads for the room
with the two Buffalo men.  He gets there and
 finds them back in their
parkas, bomber hats, and mittens.  They are
 jumping up and down,
cheering, yelling and screaming like mad men.
 The devil is dumbfounded,
"I don't understand, when I turn up the heat
 you're  happy.
Now its freezing cold and you're still happy.
 What is wrong with you two?
The Buffalonians look at the devil in surprise,
 "Well, don't you know?
If hell froze over, that must mean the Bills won
 the Super Bowl.
