Get your tickets, because it's semifinal time at the old playing field and we've got a corporate box from which to watch all the action. That's right, we're talking sport, and specifically the challenges facing the categorisation and inclusion of trans and intersex athletes. It's a pretty in-depth chat, so make sure you stock up on soggy hot chips at half time. This episode's mistakes include:

• No health and dietary warnings about chessboards.
• Started with a joke, ended with a joke, but in the middle... not so much.
• 1x1 actually equals 2.
• Egregious factual inaccuracies.
