From the tank where we put all our spare podcasts (it is not really a tank of any kind), we present Podcast 156, which we recorded two weeks ago and is thus built around questions posed on March 15 by people on Twitter, some of whom were so greedy and megalomaniacal they posted a number of questions. You'll have to listen to it to find out which ones inspired us, and which ones didn't, and whether being a retired headmaster is harder than being a nationally known stand-up comedian.
