Meine Frau macht mich verrückt(1982)

Master builder Bruno Kippnagel brings home his regular table acquaintance, the clever Egon Albert, who has a perfect command of the 'art of eloquence', to help him bring his somewhat over-excited wife back down to earth. But instead, Egon forms an alliance against him, relieves him of several marks and even kidnaps his maid Lotti.
