"Engineering Improvements" joke

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, he should never
have gotten down there; send him 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?"
