M rating? Really? The most offensive thing shown all season was a blurred shot of Heather's chest, which was still in the US airing. The part when Lindsay curses was the only change that cheapened the story in any way.

And these sexual themes you're referring to are innuendos that go over the heads of most kids. Every show now tends to have a few to appeal to adults who might have it on in the background.
