At the end of the episode, an elderly man can be seen in the audience playing up to the camera. A lady to his right can be seen apparently telling him they're in shot, which causes him to start waving his arms in the air. Realising that the shot is behind him for an overall view of the audience (presumably seen via overhead monitors) he turns to the camera and begins smiling and waving to the viewers.
This episode has two credited directors, with both John Burrowes and Tom Corcoran listed.
