The Comedy Lab has been the springboard for shows like Modern Toss, as well as showing original material by everyone from Ricky Gervais to Peter Kay. Tonight, Anna & Katy (Anna Crilly and Katy Wix) present a one-off sketch show, ploughing such wilfully peculiar furrows as a German hospital soap opera, featuring a cameo from primetime comedy type Lee Mack; a deeply awkward village prize-giving event; and a pair of Liverpudlian teenagers obsessed with measuring things. Like most oddball comedy, that all sounds rubbish on paper, but it's actually been very nicely observed and deftly executed.
