An engineer dies and goes to heaven.
However, when St. Peter meets him at the gate he says, "Wait a second! You're in the wrong place! Beat it!"
So, the engineers goes down to Hell, and gets settled in.
He soon becomes dissatisfied with conditions there, and begins to make improvements. Before long, there's running water, flush toilets, escalators, and even air conditioning! The engineer is a pretty popular guy.
One day God calls Satan on the telephone and says with a sneer, "So, how's it going down there?"
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 right away!"
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!"
"Oh, yeah?" the Devil replies. "Where are you going to get a lawyer?"
