This attitude of not letting children hear swear words or sexual innuendos or see nude women has got to stop. Don't get me wrong, I'm not suggesting we go around handing out porn mags to 5 year olds, but we do need to stop worrying about it.
I'm 29. When I was 6 every kid in the playground had a full repertoire of swear words to hand. They were all familiar with fuck, shit, piss, bastard, etc, and they all used them frequently (and appropriately) when the teachers weren't around.
Likewise, every kid has at some point seen their parents naked. They already know what a naked human being looks like. Keeping them from seeing nudity isn't going to prevent anything.
Likewise, I think its extraordinarily insulting to children to everywhere to suggest even the youngest of kids would hear "where do you like to stick your saussage?" and immediately consider porking the nearest little girl.
Adults everywhere need to learn what their kids are really like before wasting time on this nonsense.
