To lighten the tone, my favourite joke about engineers :wink:
Three engineers are sitting around over a beer, arguing about what type of engineer was in charge of the design of the human body.
The electrical engineer believed that the human body was obviously designed by an electrical engineer, because the nervous system acts as a communication system and control system, and the brain is the best computer ever invented. The mechanical engineer thought that was fine as far as it went, but the body couldn’t manage without the complex mechanisms which made up the arms, legs, trunk etc. But in the end, they were persuaded that a civil engineer must have been in charge – because only a civil engineer would run a waste pipeline through the middle of a recreational area…
