Two blondes waiting at the Pearly Gates strike up a conversation.

"How did you die?" the first blonde asks the second.

"I froze to death," says the second.

"That's awful," says the first blonde.   "How does  it feel to
freeze to death?"

"It's very uncomfortable at first," she answers.  "You get the
shakes,and you get pains in all your fingers and toes. But
eventually, it's a very calm way to go.  You get numb and you
kind of drift off, as if you're sleeping.  How about you?  How
did you die?"

"I had a heart attack," the first blonde says. "You see, I  knew my
husband was cheating on me, so one day I showed up at home
unexpectedly. I ran up to the bedroom, and found him alone watching
TV.  I  ran to the basement, but no one was hiding there.  I ran to the
second floor, but no one was hiding there, either.  I ran as fast as I
could to the attic, and just as I got there, I had a massive heart attack
and died."

The second blonde shakes her head. "What a pity.  If you had only
looked in the freezer, we'd both still be alive."
