An engineer had died, and reported to the pearly gates. St. Peter checked his dossier and said, "Ah, you're an engineer -- you're in the wrong place."
So the engineer reported to the gates of Hell and was let in. Pretty soon, the engineer got dissatisfied with the level of comfort in Hell. He started designing and building improvements. After a while, they had gotten air conditioning, flush toilets, and escalators . The engineer was by now a pretty popular guy.
One day God called Satan up on the telephone and said with a sneer, "So, how's it going down there in hell?"
Satan replied, "Hey, things are going great. We've got air conditioning, flush toilets, and escalators, and there's no telling what this engineer is going to come up with next."
God replied, "What??? You've got an engineer? That's a mistake -- he should never have gotten down there; send him up here."
Satan said, "No way! I like having an engineer on the staff, and I'm keeping him."
God said, "Send him back up here or I'll sue."
Satan laughed uproariously, and answered, "Yeah, right! And just where are YOU going to get a lawyer?"
