Rüdiger refuses to believe this and spends a lively evening partying with Mona, during the course of which she confesses to him that she actually likes Rüdiger because he's on TV. But that doesn't stop the fun. Rüdiger is determined to continue seeing Mona.

In the talk show, however, he then ventures a few daring theses, which cause a lot of public dissent, much to the displeasure of the advertising agency.
