 In the German dubbed version Otto and Gretchen Mannkusser are from  Denmark and not from Germany, they speak with a Danish accent. In  this episode Ottos nephew Willy (a typically German name) from  Germany visits him. When Francis tries to talk with Willy (his name  in the German dubbed version is Björn), it is a little bit confusing  for German viewers that Francis has a German dictionary and not a  Danish one.
