An engineer dies and goes to heaven, presenting himself before St. Peter.  St. Peter looks in the great book and can't find the engineer, so he sends the engineer down to hell.  After a few days in Hell, the engineer decides to make some improvements, running water, flushing toilets, air conditioning, and stuff like that.

God eventually calls up the Devil, and says, "Devil, how are things down in Hell?"  Satan quickly responds that things are going great.  God is shocked by this and asks how that could be.  The Devil responds, "You sent us this engineer and he's designed all these improvements for us."  God quickly says, "send him back up to us, you weren't supposed to get an engineer".  The Devil says, "No, I kind of like having an engineer  on my staff."  God says, "If you don't send him back, I'll sue."  To which the devil laughs, saying, "Where are you going to get a lawyer?"
