you've got a killer scene there, man
You spend some time hanging out with a Californian and you learn a lot about how the English language can be mutilated.
However, that Californian will turn that around by saying "you spend some time hanging out with a New Yorker and you learn a lot about how funny people can sound when they don't talk just like you."
It's not about accents, per se, but about inflection and word usage. It's a dialect thing. Ok, it is an accent thing, too. I mean, no one thinks they have an accent. But when you pick up the phone and talk to a person on the other side of the country and they sort of snicker at the way you say cawfee, you realize that while you may sound perfectly ok to your fellow Long Islanders, you sound pretty damn funny to a guy from Sacramento.
And maybe the guy from Sacramento doesn't exactly have an accent, although he stretches some vowels out and lingers on certain consanants, and kind of sounds like Jeff Spicoli sometimes, he does use certain words that let anyone who talks to him know precisely what part of the country he's from.
The thing is, New Yorkers rarely deny they have an accent. Same for people from Boston or Fargo or Texas. But ask a Californian (especially a Northern one) and they will deny to their last breath that they speak anything but perfect, unadulterated English when they actually sound very much like they learned how to speak from watching Cheech and Chong's Up in Smoke.
Stop living in denial, Californians. Ya'll talk funny.
Really, I'm just trying an east siiiiiiide/west siiiiiiide fight here.
