The news reporter of "Münster Aktuell" interviewing people on the streets of Münster says: "And back to my colleague Dominic Müller in the studio." Dominic Müller is the director of this episode of Wilsberg.
The German title of this episode "Überwachen und belohnen" (Engl. "Discipline and Reward", French "Surveiller et récompense") might be a nod to Michel Foucault's famous work "Discipline and Punish" (O: "Surveiller et punir", German: "Überwachen und Strafen") by reversing the title.
