Love Cabin Pressure so much! The dc and I are pretty much word perfect, we've listened to them so often! Did anyone hear the John Finnemore episode of the 'My Teenage Diary' series on R4 recently? It was very funny and rather endearing.
I like the Souvenir Programme too, amd agree with a pp that the exam question sketch is hilarious. Also love the goldfish/Neptune one and the one with the adventurers having to solve the riddle to get through the gate. 
JF just seems so lovely too. I can't imagine him not being a nice person in rl .
