This episode is hilarious just for that line. Shaun Pye delivered the line with comedic perfection, proving that his role in this season is just as vital as the last. I've never had this kind of attachment to a tv series before. I feel like I need everyone I know to watch this series just as a public service really. So that other people can experience the joy it brings me every time I watch it.
In this episode, David Bowie makes a mediocre on-screen cameo, which is quite funny and all but to see the full extent of Bowie's comedic talent you really need to watch the special features on the dvd to see the off-screen interview where he talks about the phrases he has coined over the years with perfect conviction. I didn't even realise he was joking until I really paid attention to what he was saying. David Bowie is hilarious.
