Since 2002 the broadcaster WDR has produced a Tatort set in Münster. Its two investigators are the police detective Frank Thiel and the forensic pathologist Karl-Friedrich Boerne. Thiel rents an apartment in Boerne’s building, so the two men are also neighbors. They solve murders together, they mock each other, and they say Sie to each other. In their 20th case, broadcast in September 2011, they drink to brotherhood and say du for one evening. The next morning they wake up with a hangover, and they are back to Sie. Before the broadcast, an interviewer asked the actor Axel Prahl whether the two would ever say du for good. Prahl answered: Keinesfalls! Not at all! The Münster episode Fangschuss had about 14.6 million viewers in 2017.
