Zack and Miri Make a Poster

So, these are the posters everyone's been talking about.

I can understand why the MPAA banned the first one. Come on, guys. Didn't you see This Film is Not Yet Rated. Women can't be shown as enjoying oral sex. It's in the Torah.

But what about nudity? The second poster clearly features two nude representations of Seth Rogen and Elizabeth Banks. Look, their names are written in right by those arrows! I don't see how the MPAA can ban one and not the other. Hollywood is so confusing.
