Heck, I can't understand (and usually don't want to) people from Massachusetts, so it's not surprising that languages are so diverse.
I found a cute t-shirt at AnimeBoston this year. It reads "English does not borrow from other languages. English follows other languages down dark alleys, knocks them down, and goes through their pockets for loose grammar." I got it for our #1 son, an English major who is finishing Law School this year.
