An Engineer dies and goes to Heaven

An Engineer dies and goes to Heaven and St. Peter meets him at the Pearly Gates and says, "Name please." The Engineer says, "Thomas Murphy." St. Peter says, "I'm sorry, your name is not on the list, you go to Hell." So a week goes by and God asks St. Peter where Thomas Murphy is. St. Peter checks his list again and sure enough there is Thomas Murphy on the list. St. Peter calls Hell and speaks to Satan and says there was a mistake and Thomas Murphy the Engineer was sent down by mistake and that Satan will have to send him back up immediately. Satan says, "I can't do that, he has put in air-conditioning and has cold running water here now. I can't let you have him." St. Peter says, "We will sue you." And Satan says, "And where will you get an attorney?"
