Teeth get treated like an emergency. Tiernan opens on tooth-brushing as if it is a dodgy experiment, where the wrong brush can taste horrible, paint everything, or simply have no business being near a mouth. Then worms cause trouble. Since worms apparently have no teeth and unclear front ends, the host drifts into breath, dentists, and whether teeth melt or explode when brushing goes wrong. The nonsense keeps moving. The host and another voice run through Whitney Houston, listeners aged minus seven to 4,006, and a magician joke that somehow lands on Ian. Poor Ian gets protected. Instead of exposing his terrible magic, they agree it is kinder to pretend coins vanish, levitation works, and nobody has noticed the props in his pockets. Then the trick starts. A favourite Scandinavian country is requested, Norway is chosen, a number between ten and thirty is picked, and the people on the podcast get subtracted. The maths turns very serious for something so shaky. The clip cuts through the muddle while the numbers are being handled with great ceremony, so the trick stays half-clear and properly silly. Then it is back to teeth. A tooth-brushing app tries to help, but first offers seal and giant squid eating before admitting it is for sharks. Worms get a version too, which skips brushing entirely. Fair enough, if the worm dentistry was right. Humans finally get instructions, though the app mostly checks whether everyone is ready before asking who needs teeth anyway. Sensible dentistry loses. Urgent nonsense law wins.
