A trio of University engineering students were debating what sort of person designed the human anatomy.
The first student said it must have been a Mechanical Engineer. "Just look at all those joints! They are perfect levers, fulcrums and rotating sockets!"
The second student argued against this. "It HAD to be an Electrical Engineer.", he reasoned, "The nervous system is a billion low-voltage circuits operating on current generated by chemical reactions!!! ITS pure genious!!!"
The third student scoffed. "You dolts have got it all wrong", he argued, "Anyone can see it was designed by a Civil Engineer..... who else would run a toxic waste pipe straight through the middle of a recreation area!"
