This week the intellectual comedy plumbs the depths of the ocean to find some interesting facts.
Joining Sandi Toksvig and Alan Davies tonight are Aisling Bea, David Mitchell, and first-time panellist Joe Lycett. Among the topics discussed include the exact number of oceans on Earth, what it is that makes sharks scary, and what Herman Melville’s editor thought would be the best way to improve Moby Dick.
Given that we are in the ocean, who can except at least one animal to get a mention from Alan: the blue whale.
QI is on BBC Two at 22.00.
