An electrical, a mechanical and a civil engineer all sat down one day to try and decide of which of their faculties god must be to design the human body.

The electrical engineer says god must be an electrical engineer, for you only have to look at the complex nervous system powered be electrical impulses.

The mechanical engineer was sure that god must be a mechanical engineer, for the advanced mechanical systems, the heart a pump, the veins pipes and the tendons and muscles an advanced pulley system.

Finally after hearing the civil engineers arguments, both the mechanical and electrical engineer both agreed that god must be a civil engineer, for who else would run a sewer system through a recreational area!
