One day God called to Satan to mock him, "So, how's it going down there in Hell?"
Satan replied, "Hey, things are 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 was surprised, "What? You've got an engineer? That's a mistake. He should never have gotten down there in the first place. Send him back up here."
"No way," replied Satan. "I like having an engineer, and I'm keeping him."
God threatened, "Send him back up here now or I'll sue!"
Satan laughed and answered, "Yeah, right. And just where are YOU going to get a lawyer?"
