Elf Lyons judges suggestions from QI elf Stevyn Colgan and Dr. Joe Latimer with Simon Watt keeping tabs on everybody from the chair.
The panel discuss smart bacteria, sentient suitcases and what the 'G' in G-spot stands for. At one point, if you listen carefully, you can hear Simon suggest he's going to do something obscene to a yoghurt.
