Just to lighten the mood lads:
Three graduate engineers were discussing who might have been responsible for the design of the human body. The first one said "Think of all the joints etc. it must have been a mechanical engineer". The second one said "No no, what about all the electrical impulses and nerves etc? It must have been an electrical engineer". The third graduate was shaking his head, "You are both wrong, the human body was designed by a civil engineer – who else would run a waste pipe through a recreational area"?
