Go Go" (one of a series of card games he has made up) with two doctors, Mr Best (Pemberton) and Dr Simon (Gatiss), who are his childhood friends, in Series 2 and helps friend Lance get a new arm attached in Series 3.

Owen Fallowfield (Gatiss), a mortician who loves his job, but is fired in Series 3 when certain activities are seen to have been inappropriate. Glen and Barry Baggs (Gatiss and Pemberton), debt collectors who are not very good at their job, especially the obese Barry (Pemberton), who is very childish and in permanent need of food.

Pop (Pemberton) is a lecherous Greek, the world's seediest landlord and its worst father, to his cringing sons Richie (Shearsmith) and Al (Gatiss). In Series 1 he disowns Richie after nine Maverick bars were stolen from his newspaper booth, and in Series 2 he ruins Al's chances of a relationship with a nurse called Patricia (Sian Gibson). Aside from owning a string of newsagents' and some tenements, Pop also owns a strip club which features in Series 3. When would-be tenants refuse to sign his contracts, he denounces them as being homosexual until they sign. In the 2017 specials, he returns to visit Al who is now married to Patricia with whom he has two children. Whilst his wife wishes Pop to leave, Pop decides to visit Richie at his delicatessen, where he forces him to anally receive an entire jar of piri-piri olives and nine Picnic bars (since Mavericks are no longer made). In a fantasy sequence, Al's wife dares him to fit in the olive jar, which he magically does and is trapped by Richie, declaring "I've got you". However, in reality, Richie has murdered Pop just as Al and his wife arrive. They are last seen glancing at a mincing machine as a way to get rid of Pop's body, presumably in reference to Hilary Briss's "special stuff". Christopher Frost (Shearsmith), store detective. Frost is a store detective who takes his work just a little too seriously, making a special effort to look inside prams, in case "baby turns out to be a 16 piece Queen Anne Breakfast set". He
