Joking Apart S01E05

After Mark attempts to return Robert's "portable telephone", he sleeps with Tracy. He hides in the bedroom and the en suite bathroom as Becky and Robert arrive at the house. After speaking to each other on the phone from adjacent rooms, Robert eventually realises what has happened and threatens to shoot Mark. The episode concludes with Robert and Tracy's, and Becky and Trevor's relationships in jeopardy. This episode makes extensive use of what Moffat labels "techno-farce", which uses technology, predominantly telephones, to facilitate the farcical situations. Moffat considers this episode the best of the show. Discussing the series as a whole, he feels that the story ends after this episode.
