It's Christmas so this week is much more impromptu than the usual tightly scripted episodes. There's songs, laughter, rapprochement and an old man lamenting his failing sperm production. Everything you want from Christmas. Plus a proper joke, some Coldplay anecdotes and a discussion about whether aliens are religious. And a beautiful duet to end on and Rich ending up with a sore throat even though he did practically nothing in the show. Support our kickstarter at rhlstp.co.uk/kickstarter
