I found an interesting interpretation of the Wizard of Oz, where the land of Oz represents gold, and "follow the yellow brick road" becomes self-explanatory.
This actually makes a lot of sense, though some of the points are reaching for it a bit. I found it a good read, even if it is a bit like calling the Smurfs K.K.K. propaganda.
The Wizard of Oz
Enjoy.
P.S. -- What do you mean the Smurfs have nothing to do with the K.K.K.? Pointy white hats, except for Papa smurf, who wears the pointy red one. Smurfette, the typical southern belle. "Azrael"? Really! Theme music that is so blatantly cheerful, you know something maniacal must be behind it...
