This week, my recent dental surgery gets us into Niki Lauda jokes, stealth Australians and Ken Branagh’s lips. Then we talk about Hot Cross Buns: what they are, how much they cost, and why Puffy remixed the song. Then Paul takes a below-the-waist guess at what “The Old Grey Whistle Test” might be, and finally, I am proven spectacularly wrong about, well, dontists.
