Mr. Burns: (Sarcastic) 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: Stop, sir.
Mr. Burns: Don't let the Germans come after me. Oh no, the Germans are coming after me.
Man: Please stop the "pretending you are scared" game, please.
