One day God calls Satan and asks, "How's it going down there?"
Satan replies that things couldn't be better. They now have air conditioning, Wi-Fi, an elevator and a lot of other amenities. He tells God that the engineer is thinking up all kinds of ways to make things better.
God is horrified. He says "what are you doing with an engineer? All engineers are supposed to go to heaven. Send him back right now."
Satan refuses. He says he likes having an engineer around.
God is furious. He says "send him back right now or I will sue you."
Satan replies "and just where do you think you are going to get a lawyer?"
