Heard on A Prarie Home Companion (via Connecticut Public Radio) 4/27/96:

Four engineers were sitting around, debating what kind of an engineer God 
was.  (The underlying assumption says a lot about engineers right there! 
- Ed.)

The Mechanical Engineer said:
   Of course God was a mechanical engineer.  Look at the marvelous
   construction of the human body.  Look at the intricate detail,
   the sophisticated joints, the ability to absorb stress.  Surely
   God is a mechanical engineer.

The Electrical Engineer disagreed.  He said:
   Look at the complex electrical circuitry.  The underlying basis
   for the operation of the body is all electrical.  Surely God is
   an electrical engineer.

The Chemical Engineer chimed in:
   Of course not.  The underlying basis of the human mind and body
   is chemical.  We are just beginning to understand that moods,
   emotions and perceptions are chemically based... and yet, this 
   is the most sophisticated, delicate and intricately-balanced
   chemical mixture ever.  Surely God is a chemical engineer.

The Civil Engineer had been silent throughout this debate; now the
others turned to him.  After a brief pause, he stated:
   You are all wrong.  God is a civil engineer.  Who else but a
   civil engineer would install a waste-disposal system right in
   the middle of a recreational area?
