An episode with a first and a last. The first Doctor Who episode to mention Gallifrey and the last one to be broadcast in a Toby Hadoke free world. Your host was born midway between this and episode four, so if everyone looks slightly less irritated and isn't looking over their shoulder worried they're going to be ambushed by a baby with lots of inane questions about cast lists then now you know why. It's a fun episode, this, with one of the worst performances in the show's history, and a personal connection to Toby as he has worked with someone who was standing very close to that terrible acting.  It's doubtful that special guest Tom Salinsky, and Toby will be choosing the Sentry as their favourite thing but hey, you never know (cue unconvincing laughter).
