Russell Brand was always on thin ice when on air. I for one won't miss him, but i think the real blame lies in the BBC for allowing it to get through. The only reason Ross and Brand are on a show together is to aim for as big a demographic as possible. Therefore, Brand trying to reach out to the younger audience blurs the line slightly for some people in the editing room. Hosts say bad things and make crap decisions like the rest of us, but it's the BBC's job to moderate what goes though. They made a bad call and the BBC should pay, not any of them.
Besides. The girl is part of a pole dancing troupe called the 'Satanic Sluts' so she pretty much had a target painted on her as far as i'm concerned.
