Der Rosenkavalier
Ochs meets Mariandel (Octavian dressed up as the maid again).  He tries to get "her" drunk, but "she" shyly sings “Nein, nein!  i’ trink kein Wein.” (“No, no, I don’t drink wine”).  Ochs thinks "she" looks like Octavian.  Then strange figures of people appear at a window.  Then Annina comes in and says she is Ochs’s wife whom he has deserted.  Then some children come in and say that Ochs is their father.  Ochs is very embarrassed when Faninal comes in and says Mariandel is his fiancée.  He tells the people he has never seen Faninal before.  Then the Marschallin appears and also the police.  The evening is a disaster for Ochs.  The Marschallin tells the police it is just a joke.  She sends Ochs away.
