The Simpsons Movie

Last night I saw that new Simpsons movie. It was OK overall but the movie made me wonder about those movie ratings. The Simpsons was PG-13.

After the movie was over a bunch of us noticed something was missing.
Marge Simpson's two smoking sisters !!! There were nowhere to be seen in the movie. The woman who sat in front of us was telling us that the reason the sisters were overlooked was that they were, well smokers. If the movie showed them smoking cigarettes ( which is more/less a trademark for them ), then the movie would have gotten a "R" rating.

But the movie rating people had no trouble with the scene in the movie where the Otto bus driver character was seen smoking a bowl, and then there is that scene of Bart Simpson's, well....

So lets see here...a scene of people smoking cigarettes is considered rated "R" now but a scene of someone doing drugs is rated "PG-13"?????

Hey I know its just a cartoon but still it makes me wonder if those people who rate the movies for content, if they arent smoking those funny cigarettes themselves !!
