I grew up in pittsburg and now live in Michigan. I get a lot of crap for how I talk. Child is "chowd" and Don and Dawn are pronounced the same. Not to mention all of piperdr's pittsburg-ese. Let's go 'quins!!
I do give all the overseas guys accents, especially with 'mate' and 'cheers'. Usually add Tallyho at the end in my head too

And "I know enough to be scared of KaiserSoze"...
