60 - The Pounding in My Head (S4, Ep15)
We watch "Planet of the Dead" (Series 4, Episode 15) where the Doctor catches the Knight Bus but gets off at the wrong stop. Whilst there, the Doctor gets to know his fellow passengers including Lady Christina who wants to steal his heart and Barclay who just wants to get out. After a couple of helpful flies get squashed, the Doctor gets pooped and decides to drive back to Earth before it gets pitch black and before UNIT can plug up his wormhole.
