bleepity, bleeping bleep

How can a channel bleep out the word "ass" during the day and then the same channel later that day (9pm to be exact) run Sex and the City with full nudity and a ton of F bombs all over the place?

I can't have Carrol Shelby talk about "added downforce to keep the ass-end of his car on the ground" but the slutty old chick on Sex and the City can parade around buck naked for half an hour?

Brits are strange.
