Maybe they learned all this at the liberry? 
Mr. Muse and I were discussing this one last night-- we decided it would be neat to have a smoothie bar (because, you know, lots of fruit and berries go into smoothies) with books for people to read as they drank called Liberries.
I'd be a regular customer!
Me, too! That sounds great!
I bet if you got jaxsue and me in the same room we would have completely different accents - hers from North Jersey and mine from South - and neither one of them would sound like the Jersey Shore people (most of whom were actually from Long Island and parts of NY if i remember correctly).
"Yous" as a plural of you is definitely used where i live, though. I hate it. Mostly it comes out sounding more like “yiz” than “yooz” in my area. “Wha’-c’n-I-getchiz?” {{shudder}} It's accepted, i suppose, as dialect; but horribly wrong.
