An engineer dies and goes to hell. After a while, the engineer gets dissatisfied with the level of comfort in there and starts designing and building improvements. After a while, hell has air conditioning, ingflush toilets, water fountains and escalators - making the engineer a pretty popular guy.
One day God phones Satan up and asks with a sneer: "Hey buddy, how's it goin down there in hell?"
Satan snickered back, "Things are going great actually. We've got air conditioning, flush toilets, escalators and the works. Hell (no pun intended), there's no telling what this engineer guy is gonna 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 back up."
To which Satan replied, "No way dude. I like having an engineer on staff, I'm keepin him."
God retorted, "Send him back up here or I'll sue."
Satan laughs loudly and answers, "Yeah, right. And just where are you gonna find a lawyer?"
