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?"
