Traditional fairy-tales tend to focus more on the idea that if you interact with strangers or do anything out of the ordinary, you will die horribly :P (At least that's what I noticed when reading Aesop's fables recently).
Also the idea that the letter of the law is more important than the spirit, and sometimes the idea that even if you are unintelligent and lazy you'll still win so long as you're obedient.

Tim Minchin fans may recall him mentioning Scooby Doo in a similar light in his beat poem Storm, and it's been brought up on Less Wrong before.
When viewed in this light, Scooby Doo really is like an elementary version of Methods of Rationality.
