So the engineer reports to the gates of hell and is let in. Pretty soon, the engineer gets dissatisfied with the level of accommodations and starts designing and building
improvements.

After a while, they’ve got air-conditioning and flush toilets, escalators, elevators and so on … and the engineer is a pretty popular guy.

One day, God calls Satan on the telephone.

“So, how’s it going down there in hell?” God says.

“Hey, things are going great. We’ve got air-conditioning and flush toilets and escalators. There’s no telling what our engineer is going to come up with next!” Satan says.

“What? You’ve got an engineer? That’s a mistake — he should have never gotten down there. Send him back immediately!” God says.

“No way! I like having an engineer on the staff — I’m keeping him!” Satan says.

“Send him back up here or I’ll sue!” God says.

Satan laughs uproariously and answers:

“Yeah, right. And just where are you going to get a lawyer?”
