Love this nice change of pace

A Sarah Jane Adventures skit with Ronnie Barker, K9, Slitheen and some good gentle humour - I loved the two Ranis gag! And then there are a whole lot of fart jokes. Its not great but then how much can you really fit into a 5 minute mini-SJA? Its a sign of how big a cultural force Doctor Who was at the time that its spin off show could command such a presence with a major celebrity at the head of the BBC's Red Nose Day celebration. And nice that the main show could defer to its spin off for one of these mini eps.
