Zärtliche Chaoten (1987)

Ricky, Walter, and Edmund, three not-so-successful and chaotic Daydreamers, meet after they all get fired from the set of the new Winnetou production. On their way to the next town they meet Rosi and all three fall in love with her immediately. After an intimate party for four, Rosi finds out she's pregnant by one of them. Until they can be sure which one is the father, all three try to help her out however they can and get the necessary money for the baby. They will try absolutely anything, no matter how chaotic will be the outcome.
