When Prinses Beatrix is confronted by outspoken artist Wim T. Schippers in a scene set in 1967, he uses his made up expression 'pardon, reeds' which he didn't use until the early Seventies. Further more, he also uses the made up word 'Joe' (a combination of the personal pronouns 'Je' and 'U'). This expression Schippers did not start using until the mid Eighties, during his radio program 'Ronflonflon avec Jacques Plafond'.
