I don't know if Kermit is a commie, but I think he just might be a bit of a jerk.
A few days ago, I was in Munich, Germany. Who should happen to be visiting Germany at the same time but Kermit and Piggy, promoting their movie. Kermit and Piggy did an interview on a German morning talk show. Unfortunately, the poor creatures didn't speak German, and the interviewer didn't speak English. (Side note: Peter and Stewie in "Family Guy" speak German in nearly the same voices as they speak English.) So there was an interpreter to help, but the interpreter didn't help much.
As the interview was concluding, the interviewer reminded the audience of the name of the movie: "Die Muppets." With a German pronunciation, it sounded like "Da Mooputs."
"Ah, yes, da Mooputs," Kermit said, mimicking the inteviewer and acting put off that "muppets" had been so badly mispronounced. I wondered whether any viewers caught the tone of sarcasm.
