Devil in the Details

One day, an engineer died and went to heaven, but St. Peter said “I can’t let you in because your name is not on the list.”
So the engineer went down to Hell and was let in. He stayed there for a couple of days and decided that it was too hot and everything was inhospitable. So he built flushing toilets, air conditioning, running water and a lot of other things.
One day God calls down and says to Satan, “So Satan, how’s it down there in hell?”
Satan says, “It’s great! I’ve got an engineer down here, and he has built air conditioning, running water, flushing toilets, and I don’t know what else he’s gonna build next!”
God responds, “You’ve got an engineer down there? That’s a big mistake! Send him up here right now!”
“No way,” said Satan. “This is the best thing that’s ever happened to hell.”
“Send him up, or I’ll sue your ass!” threatened God.
With an evil smirk, Satan notes, “Now just where do you think you’re gonna get a lawyer?”
