Alright, I haven't actually seen Ratatouille. I have, however, seen the commercial.
And I got to thinking.
The gist of the story as I understand is this:
A rat who is great at cooking, teams up with a person who is great at... being a person. Basically, rats can't get employed as chefs, because they're rats. The person sucks at cooking, however he puts on a show, and pretends to cook, while the rat cooks the food.
This seems like some sort of symbolism for the world of celebrity.
eg. Britney Spears (here we go again...). Britney Spears is the "person". While her song writers, producers, and PR officers, etc, are the "rat".
