Could David Walliams play the Celestial Toymaker? Photograph: Dave Hogan/Getty Images
Last week, it was one of the Double Take Brothers. The week before that, it was Tim McInnery, aka Blackadder's Captain Darling. We've had Peter Kaye as Abzorbaloff and the League Of Gentlemen's Mark Gatiss as Professor Richard Lazarus. There was even a vicious rumour that the Van Hoffs in the Voyage of the Damned Christmas Special were originally written for Lenny Henry and Dawn French. And, of course, Catherine Tate is his new, feisty assistant.
What is it with Doctor Who and comedians? The latest series is turning into a bizarre guessing game, as viewers try to look beyond the latex to work out which classic comedy they recognise the baddie from. Among my friends, it's evolved into a wishlist where we try to outdo ourselves with the perfect role for the least likely comedic cameo. David Walliams as the Celestial Toymaker? Bobby Davro as a Cyberman? By far the best suggestion has been Alexei Sayle as Davros. Given his current track record, I wouldn't put anything past Russell T Davies. Who do you think would make the best Doctor Who baddie?
Oh, and I promised Andrew, who came up with the Alexei Sayle idea, that I'd sign off with his Return of the Two Ranis gag. But I just can't bring myself to do it.
