Horst: [threatingly] We Germans aren't all smiles und sunshine.
   Burns: [recoils in mock horror]
          Oooh, the Germans are mad at me.  I'm so scared!  Oooh, the  Germans!
          [hiding behind Smithers]  Uh oh, the Germans are going to get  me!
   Horst: Stop it!
   Man 2: Stop, sir.
   Burns: Don't let the Germans come after me.
          Oh no, the Germans are coming after me.
   Man 2: Please stop the `pretending you are scared' game, please.
   Horst: Stop it!  Stop it!
   Burns: [brief pause, then resumes]
          No!  They're so big and strong!
   Man 2: Stop it.
   Horst: Stop it, Mr. Burns.
   Man 2: Please stop pretending you are scared of us, please, now.
   Burns: Oh, protect me from the Germans!  The Germans...
   Horst: Burns, STOP IT!
