Three engineers are in a bar discussing which school of engineering god belongs to, the mechanical engineer goes first;

“God’s a mechanical engineer, look at the bones and muscles and how they interact and move.” The electrical engineer is shaking his head;

“God’s an electrical engineer, look at the nervous system and how the brain is wired, that’s electrical engineering.” At this stage the civil engineer has a wide grin on his face;

“God’s a civil engineer, who else would run a waste pipe through a recreational centre?”
