An engineer dies and reports to the pearly gates. St. Peter checks his dossier and says, 'Ah, you're an engineer -- you're in the wrong place.' So the engineer reports to the gates of hell and is let in. Pretty soon, the engineer gets dissatisfied with the level of comfort in hell, and starts designing and building improvements. After a while, they've got air conditioning and flush toilets and escalators, and the engineer is a pretty popular guy.
One day God calls Satan up on the telephone and says with a sneer, 'So, how's it going down there in hell?' Satan replies, 'Hey, things are going great. We've got air conditioning and flush toilets and escalators, and there's no telling what this engineer is going to come up with next.'
God replies, 'What??? You've got an engineer? That's a mistake... YOU never get engineers down there; send him back up here.' Satan says, 'No way. I like having an engineer on the staff, and I'm keeping him.' God says,'send him back up here or I'll sue.' Satan laughs uproariously and answers, 'Yeah, right. And just where are YOU going to get a lawyer?'"
