German Unity Day
The young couple, Rita and her husband Michael, cannot afford an apartment and live in Rita's child's room. Michael is a supporter of Chancellor Willy Brandt and moreover was raised in East Germany, which arouses Alfred's suspicion of him being a Komsomol, a Bolshevik hyena and an anarchist. Michael's parents still live in East Germany; as retirees they are allowed to visit their son and his new family in the episode "Besuch aus der Ostzone" ("Visit from the Eastern Zone"), an episode which exists both in black-and-white and colour and is usually aired on German Unity Day.
