Richard is excited about recent developments in robotics, but he doesn’t have time for stand up (or any stand up). His guest is the remarkable comedian, singer and YouTube sensation Sooz Kempner (plus some interjections from her mum). They talk about personifying a times table, being snubbed by opera singers, how to satirise the almost unsatirisable Tory MPs, why Twitter has gone down the toilet, responding to trolls and reply-guys, the wonder that is the fans of Dr Who and what it’s like stepping into that Universe (and having your head crushed by a Cyberman) and why dressage trumps the Edinburgh Fringe (and will Rich ever return?)
