A software salesman died.  He approached the pearly gates where 
the attendant told him he had a choice of heaven or hell.  First 
he visited heaven, where everyone was flying around playing 
harps.  Pretty boring.  Then he visited hell where a toga party 
was in progress with plenty of good food, music, etc. and 
everyone seemed to be having a blast.  

"I'll take hell," he said.  He was immediately thrust in the 
fiery depths and a dozen demons set upon him, poking him with 
their spears and pitchforks as he roasted, his screams joining 
those around him.  Just then Satan walked by.  Between his 
screams he managed to gasp out, "Hey, what happened to that 
party I saw going on?"

"Ah," said Satan. "You must have seen our demo."
