In Loriot’s cartoon sketch Herren im Bad, first broadcast on 15 June 1978, Dr. Klöbner and Herr Müller-Lüdenscheidt find themselves in the same hotel bathtub, because Dr. Klöbner got the room number wrong. The two men argue in a measured tone, addressing each other as Sie. Wissen Sie, dass viele Menschen überhaupt kein Bad besitzen? Do you know that many people do not own a bath at all? Sie lassen sofort die Ente zu Wasser! You will put the duck in the water at once!
