I have a good friend from Bawston with an accent you could cut with a knife, who married a lady from Alabaaama with a Suthuhn accent reeking of magnolias. I know the secret of their relationship - neither can understand a single word the other one says. ;-)
When strangers look at me funny, or have an awkward pause on the phone after they ask where I am originally from... and I answered New Jersey, I come back in my best mobster voice, “Whaddaya got a F***in’ problem wid dat?”
