Possibly copyright issues on the clips used, rather than the swearing [i]per se[/i]
Newsnight were quick off the mark though. They used a bleeped version of that vid for their closing credits sequence, last night. (available on iPlayer, in that case, for a while at least). Even referred to it as a 'mash up'.
Since I'd already seen it, here on AB, the closing credits sequence they did to go with the Osbourne-burger photo still ranks as the funniest, to date.
