Spoiler Warning!!!
If you haven't seen the movie yet or don't want a joke spoiled, don't read any further!!!!

I know there has been a lot of talk in the past about what is and is not acceptable in terms of depicting children in sexual situations.  As I remember there was quite a bit of controversy around whether a fairy can have her breasts exposed.

And if remember correctly there is a law stating that you cannot show any minor (real, drawn or computer generated) naked or in a sexually suggestive pose.

So I saw The Simpsons movie yesterday (very funny btw) and there was a sight gag about covering naked Bart's penis.  But they showed it anyway.   While it was very funny, and absolutely innocent, it made me wonder if that was against the law or not?
Has anyone else been curious about that or do I have too much time on my hands?
