  Come on Alan ! ;-)
  Don't send him to the basics, is much easy considering the gnd and the
Vcc with 0 impedance , gnd because is ground and Vcc because it cames from
a zero output impedance stabilizer, so you have two resistors connected in
parallel because vcc and gnd are equal to 0 ( as impedance and not as
values )
  Of course the crude reality is a little different...
