Three engineers were having a debate at to what type of engineering background God must have had in order to design the magnificent human body.
One engineer said, "He must be a mechanical engineer. Who else could design such an efficient respiratory system to move air and sweat glands to cool the body!".
The second engineer responded, "No, I think God must have been an electrical engineer. Only an electrical engineer could have designed the brain and nervous system to transfer electrical responses so effectively!"
Finally, the third engineer interrupts saying, "You're both wrong. God has to be a civil engineer. Who else would run a waste disposal lines right through the middle of a recreational area!"
