many references to secondary characters and locations from his previous BAFTA winning show Press Gang into Chalk. For instance, the Chalk character Eric Slatt refers to his neighbouring school Norbridge High, run by Mr Sullivan: these were the names of the school and deputy headmaster in Press Gang. The scene where Slatt is being given instructions by wire is taken from the unfilmed Press Gang movie Dead Line. The pornographic video Lesbian Spank Inferno, owned by Dan McGill in the final episode, is later referenced in the Coupling episode "Inferno". In an interview with The New York Times, Moffat admitted that the video is inspired by his then-new partner, Sue Vertue, finding a similar video in their VCR.

Moffat told The Herald that Slatt was inspired by a real person: My main character, the deputy head, is a manic git, and he's based on a guy I never actually met and is therefore being denigrated terribly. He had already retired by the time I started but I used to get a lift to work from his wife, who still worked there. And she would tell me stories about him with the affectionate disdain of anyone who has been married for more than a year. In the staff room, all these bitter teachers who hadn't been promoted would describe him as someone who would only briefly consider stopping short of invading Poland if he got the chance. I've since found out that the real man is actually a very nice bloke. Ptaszynski had attempted
