In our twenty-third podcast, in light of Radovan Karadzic's arrest for being an acupuncturist, we discuss the amazing disguise possibilities of growing a beard, Christian Bale getting bail, the key differences between a Milton Keynes NCP call centre operator and a concentration camp guard, and conduct a calm, reasoned, evidence-based debate about homeopathy. We also reveal details of the first ever live podcast with an audience in Edinburgh.
