In this first programme, boxing champion Chris Eubank is tasked with memorising hundreds of facts about Jurassic dinosaurs, Strictly Come Dancing legend Len Goodman is given '90s American hip-hop to master, Love Island winner Amber Gill is assigned British birds, Naked Attraction presenter Anna Richardson is tasked with the solar system, while actress Nina Wadia must memorise the human skeleton.
