LMAO!! Normally, I don't have too much of an accent, but you should hear me when I get really, really mad. I sound like one of the Super Fans from SNL.
I never really believed in a "Chicago accent" until I worked at Gino's East in Rosemont for a few months. My first night on the phone people were calling up ordering "saahs-age" and I was a believer.
OMG! SOME OF THE BEST PIZZA EVER!
I started noticing when I was in college and many of my friend were from the burbs. Definite accent, but I love it.
