A civil engineer died and went to Hell.
Dissatisfied with the level of comfort available, he started designing things and making improvements all over the place.
After a while, the engineer was a pretty popular bloke.
One day God rang and asked Satan, "How is it down there?"
Satan replies, "Excellent!. We have air-conditioning, flushing toilets and escalators. I have no idea what this engineer is going to do next."
God was horrified. "What! You have an engineer? That is a mistake - he should not be down there under any circumstances! You know all engineers go straight to Heaven. Send him up here!"
Satan replied, "You must be joking! I like having an engineer on my staff. I am keeping him."
God thundered, "Send him back up here or I will sue your arse off."
"Funny bugger," Satan laughed, "and where are you going to get a lawyer?"
