Three engineers were having lunch one day, and the talk turned philosophical:
The first engineer wondered what kind of engineering help God had when He
created humankind, and proposed "It must have been a mechanical engineer --
just look at the variety of movements in all the joints of the body!"
The second engineer responded, "No, I think it must have been an electrical
engineer -- think of how the brain controls all the functions of the body via
electrical impulses."
The third engineer thought for a moment about his friend's opinions, and then
said, "No, it had to be a civil engineer -- who else would run a sewer line
through a recreational area???"
