Legendary Peanuts creator Charles Schulz was from the Minneapolis-St. Paul area and they totally capitalize on it. Who wouldn't? What a great opportunity for his legion of fans.
The wah-wah adult voices in the 'Peanuts' TV specials and movies are just as unforgettable as the characters themselves. Although it's not know why the trombone with a plunger over the bell was used to convey the adult speak in the world of Charlie Brown, it's still funny.
