The fourth episode features a scene where Mark jams his dressing gown in the door and is forced to hide naked in his new neighbour's flat. This sequence was Moffat's revenge for Bathurst's late arrival at the series one press launch at the Café Royal in Regent Street, London. Moffat threatened that if they ever did a second series he would write a whole episode in which Bathurst was naked. After being mistaken for a flasher, Mark is punched by his neighbour's brother. When he awakens he is confronted by a man (Kerry Shale) in a red polo neck jumper who claims to be "his very best friend". In the fifth episode it transpires that the man, who identifies himself as Dick, is the personification of Mark's penis.
