Story

It concerns two little boys,  one  a  proverbial grumbler for whom nothing is good enough, and the other  a  congenital  optimist  for  whom  nothing is impossible.
 

The first little boy, the grumbler, is put in a room full of beautiful toys. He comes out an hour later tear-stricken and miserable: the dolls aren't pretty, the golliwog  is  cockeyed,  the  toy-train  doesn't  work,  the  batteries are
rundown.

The  other  little fellow is put in a room full of horse manure. An hour passes, two hours pass, and there is no sign of him.  They open the door and he is seen rummaging around in all that horse manure.  So they ask him  what  the  hell  are you doing?  He gives a beaming smile and says: If there  is  so  much  horse  shit, there's got to be a pony somewhere - I am looking for the pony."
