A builder dies and reports to the pearly gates. St. Peter checks his dossier and says, "Ah sorry, you're in the wrong place."
So the builder reports to the gates of hell and is let in. Pretty soon, the builder gets dissatisfied with the level of comfort in hell, and starts making improvements. After a while, they've got air conditioning and flush toilets and escalators, and the builder is a pretty popular guy.
One day God calls Satan up on the telephone and says, "So, how's it going down there in hell?" Satan replies, "Hey, things are going great. We've got air conditioning and flush toilets and escalators, and there's no telling what this builder is going to come up with next."
God replies, "What??? You've got an builder? That's a mistake! He should never have gotten down there; send him up here." Satan says, "No way. I like having a builder on the staff, and I'm keeping him."
God says, "Send him back up here or I'll sue."
Satan laughs uproariously and answers, "Yeah, right. And just where are YOU going to get a lawyer?
