i learned this from

my grandparent's neighbor when I was a kid.

MR Ducks
MR Not
OSAR
CM Wings

This was from one of my stops in West Columbia.  Foie gras, anyone?  I'M KIDDING.  (I'd never eat that stuff.)

Oh, and the stuff I wrote above translates to this:
'em are ducks.
'em are not.
Oh yes they are,
  see 'em wings?
Which translates to:
Those are ducks.
They are not.
Oh yes they are,
   see those wings?
