In the wine party scene Ulli is drinking wine with Elke on "Brüderschaft" way (around the arms and with a kiss). After Ulli realized, that he was kissing Elkes uncle Jupp instead of Elke, he said: "You could be my father". Willy Millowitsch, who was playing Elkes uncle, was actually the father of Peter Millowitsch, who was playing Ulli.
